CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation application of U.S. application Ser. No. 10/197,128, filed Jul. 17, 2002 now U.S. Pat. No. 6,853,710 entitled TELEPHONE CALL MESSAGING DEVICE. 
    
    
     FIELD OF THE INVENTION  
     The present invention relates generally to electronic communication devices and more particularly to devices for use in an office environment for transmitting and receiving messages relating to telephone calls. 
     BACKGROUND OF THE INVENTION  
     An office receptionist is nearly always responsible for answering the company telephone and writing down the name and telephone number of the caller, the date and time of the call, as well as the name of the person for whom the written message is prepared. In a typical telephone call the person answering the phone records the date, time, name of the caller, name of the person who will receive the message, and any additional information to be conveyed in the message. For the convenience of the receptionist, pads of paper with form blanks for date, time, and names and additional predefined messages such as “returned your call”, “will call again”, “wants to see you” and the like, with check boxes adjacent to the predefined messages, are available from office supply stores. Adhesive backed memo pads are also available wherein the memo can be stuck to a surface as a result of the adhesive on the underside of the paper surface. 
     Normally, the written message is placed in a message holder with employee names attached thereto, and employees pick up their messages at the receptionist desk at their next convenience. Alternatively, the receptionist might physically deliver the messages to the office of the recipient, or secretaries may attend to this task. In either scenario, valuable work time is lost while employees transport small pieces of paper with simple messages around the office. Occasionally, the receptionist needs to deliver the message immediately to the recipient, particularly if the recipient is already using the phone in his/her office, is in a meeting and does not wish to receive telephone calls, or if there is some urgency associated therewith. When immediate delivery is required, physical delivery of the message is inconvenient and distracting in regard to the receptionists other duties and forces the receptionist to forego other duties. 
     There are computer based messaging systems that utilize a personal computer for receiving telephone message data input from the receptionist and transmitting the messages to the recipient&#39;s computer via local area networks. However, if the recipient&#39;s computer is not powered on, or a network problem exists, or a power outage occurs and backup batteries are not in use, or the appropriate programs are not running on the recipient&#39;s computer, such a computer based messaging system fails to provide that which is needed, a messaging system for conveying telephone call messages. In addition, where a personal computer is not needed to carry out an employees job responsibilities, the cost of a personal computer is not justified simply for receiving telephone call messages or memos. 
     In smaller organizations wherein various employees may be responsible for answering telephone calls, it becomes necessary for each employee to have available a telephone message memo pad and write down telephone memos or messages when calls are received. Further, the memos must be delivered to the appropriate recipient, and again, a loss of working time is generated delivering memos around the office to the recipient. 
     What is needed is a device that provides added convenience to the user in creating electronic telephone messages or memos and dispatching same to the appropriate recipient immediately. Such a device should take advantage of existing office wiring and telephone systems so that installation and use thereof is relatively inexpensive. In addition, the device should include electronics to automate the entry of some of the necessary data, such as date and time of the call, as well as telephone caller ID data.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated devices, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates. 
     Referring now to  FIG. 1 , a block diagram for a telephone messaging device  10  according to the present invention is shown. Messaging device  10  includes a microprocessor  12  or microcomputer having RAM, ROM, and I/O (input/output) that comprises the controller of device  10 . Real time clock  14  provides date/time data to microprocessor  12 . Real time clock  14  includes a battery backup feature so that a power loss does not result in loss of the correct date/time. A flash memory device  16  contains sufficient storage space for storing a large quantity of data. Flash memory device  16  is contemplated as fully integrated or removable in design such as removable compact flash media cards used in current products such as digital cameras for storage of image files. Such memory devices are now very reasonable in cost for as much as  64  megabytes of storage. Audio circuitry  18  includes the necessary electronics such as a/d (analog to digital) and d/a (digital to analog) converters for microprocessor  12  to digitally reproduce audio on speaker  21  and record audio signals in digital form from microphone  23 . Alternatively, the audio electronics in circuitry  18  may be comprised of CODECS (coder/decoders) well known in the art of cellular phone technologies for efficient recording and playback of digitized audio. (It is contemplated that a reduced cost version of device  10  may be produced without audio messaging capability thereby eliminating the need for audio components  18 ,  21  and  23 ). A liquid crystal display (LCD)  20  receives signals from microprocessor  12  and responds by displaying graphical images on display  20 . LCD display  20  is a graphical electronic display device similar to those found in PDA (portable digital assistant) devices. A touch sensitive display overlay  22  input device is positioned directly over display  20  and provides a mechanism for the user to input data to microprocessor  12 . Touch sensitive display overlay  22  and related technologies are also found in PDA devices such as the Palm Pilot® PDA. A computer interface  24  provides the mechanism for microprocessor  12  to communicate with external devices such as personal computers or PDAs. Computer interface  24  is preferably a USB (Universal Serial Bus) or Firewire® (IEEE 1394) interface developed for use in inter-computer communications to provide a very fast communications link between intelligent devices. Telephone caller ID electronics  26  includes circuitry for detecting caller ID data provided by a telephone company over the local telephone lines. Caller ID electronics  26  is connected to the telephone system wiring via cable  28  and provides caller ID data to microprocessor  12  upon receipt of such information from the telephone company over cable  28 . A data communications interface  30  includes electronics for establishing communications with other telephone messaging devices identical to device  10  via data link  32 . The data communications interface  30  and data link  32  are implemented by use of technologies for sending and receiving data packets over existing power lines, telephone wiring, network cabling, or via radio frequency technologies such as wireless LAN (local area network) technologies. Such technologies are well known and one skilled in the art may readily implement any of the various communications technologies that do not require additional wiring be installed in a facility to establish communications between intelligent devices. It is also contemplated that standard networking protocols such as the TCP/IP suite of networking components are used to transmit and receive data over data link  32 . 
     Computer interface  24  is also an alternative mechanism by which alphanumeric data may be entered by the user of messaging device  10 . A computer program driver on a personal computer redirects keyboard input from the computer via interface  24  to messaging device  10  for data entry in the various textbox GUI (graphical user interface) program objects described below. 
     Referring now to  FIGS. 2-4 , a telephone messaging device  10  according to one aspect of the present invention is shown. Messaging device  10  is contained within case  34  made from plastic or other suitable material. Graphical display  20  is shown in  FIG. 2  with one display configuration or screen in accordance with the primary operating mode of device  10 . A touch sensitive overlay  22  (that is transparent) is positioned over display  20  and provides input signals to microprocessor  12  when stylus  36  is depressed on top of the overlay  22 . Software mapping techniques are implemented to associate regions of the overlay with graphical program objects shown on display  20 . A PDA operating system such as Windows CE from Microsoft Corporation is contemplated as one potential GUI solution for creation of the software and graphical programming objects discussed in relation to messaging device  10 . 
     Referring now to  FIG. 3 , a rear elevational view of messaging device  10  is shown. From this perspective, the external connections to device  10  are shown. In particular, a power connector  38 , a microphone jack  40 , a telephone system connector  42 , a USB interface connector  44 , a compact flash media card slot  46 , and a small grill area  48  behind which speaker  21  is positioned are all shown. 
     Referring now to  FIG. 4 , a front elevational view of the messaging device  10  is shown. This view depicts the slight inclination angle at which the display  20  is positioned so that it is more readily viewed by the user. It is contemplated that the angle of inclination of the display may vary over a wide range. 
     Referring back to  FIG. 2 , the various visual elements or GUI objects displayed on display  20  will now be described. As in a PDA, the underlying graphical elements shown are typical components of a GUI (graphical user interface) well known in the computing industry. A recipient drop-down listbox  50  provides a mechanism for selecting those messaging devices that will receive a message data packet created by messaging device  10 . Recipients may include individuals or groups of individuals. Defining groups is discussed below. Alternatively, listbox  50  is a “multi-select” type listbox allowing for selection of multiple entries in listbox  50  thereby enabling the selection of multiple individual recipients and/or multiple groups that will receive a particular message data packet. Typically listbox  50  is populated with names of persons corresponding to messaging devices (during setup a messaging device  10  is assigned a name corresponding to the person who will be using the device) and group names. Textbox  52  is provided for displaying caller ID information received by microprocessor  12  via telephone caller id electronics  26 . Textbox  54  displays user input information regarding the name of the telephone caller&#39;s name. Textbox  56  displays company name of the caller entered by the user. Textbox  58  is a date/time text box that is automatically populated with date/time data when a telephone call is received (microprocessor  12  becomes aware of a new telephone call when caller ID electronics  26  provides caller ID data to microprocessor  12 ). Alternatively, textbox  58  displays the date/time of a current message being displayed by device  10 . Upon detection of a telephone call microprocessor  12  obtains the current date/time from real time clock  14  and enters that data into textbox  58 . Textbox  60  receives user input data regarding the caller&#39;s telephone number if that number is different from that shown in textbox  52 . A plurality of checkboxes with corresponding descriptions are provided that enable the user with a single tap of stylus  36  on the checkbox or the text adjacent the checkbox to enable or disable the mark within the checkbox (typically an “X”) in the corresponding checkbox. These checkboxes include a FAX checkbox  62 , a MOBILE checkbox  64 , and checkboxes corresponding to a plurality of predefined messages including PHONED checkbox  66 , RETURNED YOUR CALL checkbox  68 , PLEASE CALL checkbox  70 , WILL CALL AGAIN checkbox  72 , CAME TO SEE YOU checkbox  74  and WANTS TO SEE YOU checkbox  76 . A message area  78  provides region of the display  20  wherein a custom handwritten message may be entered by the user regarding the telephone call. Information entered into the message area  78  includes additional information useful to the recipient of the message regarding the telephone caller&#39;s purpose or business. Message data is entered in message area  78  by printing or writing on the area with stylus  36  or tapping the DISPLAY KEYBOARD pushbutton  80 . Printed or handwritten messages are converted to a digital data format and the data is compressed for efficiency in storing the data to memory device  16 . A variety of compressed digital graphical image formats such as JPEG (named after the group Joint Photographic Experts Group that developed the file format), GIF (graphs interchange format) and TIFF (tagged image file format) are well known and used for compressing and storing graphical images such as the data input from touch sensitive display overlay  22  that defines handwritten messages in the present invention. Handwriting recognition software is optionally included to transform the handwritten message into alphanumeric data. Handwriting to ASCII conversion software is well known in the art. Tapping pushbutton  80  causes an alphanumeric data entry screen to appear on display  20  as shown in  FIG. 7 . Tapping CLEAR pushbutton  83  will clear or erase handwriting or typed data entered into message area  78 . A plurality of graphical pushbuttons (GUI visual program objects) are provided to activate various functional actions provided by messaging device  10 . UP ARROW pushbutton  82  and DOWN ARROW pushbutton  84  provide message navigation forward and backward in the current message list stored by microprocessor  12  and displayable on display  20 . Similarly the HOME pushbutton  86  and the END pushbutton  88  enable rapid movement to the first or last message available for display, respectively. CLR pushbutton  90  instructs microprocessor  12  to clear the display of all data in preparation for entering new data or for protecting the data from view by others. DEL pushbutton  92  instructs microprocessor  12  to delete the currently displayed message from memory. SCHED pushbutton  94 , corresponding to the word “schedule”, signals microprocessor  12  to display a reminder data input screen where the user enters date/time and message data instructing microprocessor  12  in regard to a future date/time wherein a reminder message is displayed. SAVE pushbutton  96  causes microprocessor  12  to save the message data packet for the currently displayed message into another area of permanent flash memory  16 . AUDIO pushbutton  98 , when tapped by a stylus, instructs microprocessor  12  to display an audio playback/record screen and command buttons as shown in  FIG. 9 . SECURE pushbutton  100  instructs microprocessor  12  to enable a password security feature for the currently displayed message. Upon tapping pushbutton  100 , the user is prompted to enter an alphanumeric password for the currently displayed message, and future attempts to redisplay that same message require the user to input the correct password before the message may be viewed. SEND pushbutton  102  instructs microprocessor  12  to assemble a message data packet including caller ID data from textbox  52 , name data from textbox  54 , company name data from textbox  56 , date/time data from textbox  58 , additional telephone number data from textbox  60 , checkbox data settings for predefined messages in checkboxes  62 - 76 , and data entered into message area  78  and send the assembled message data packet to the messaging device identified in the “For” dropdown listbox  50 . MENU pushbutton  104  instructs microprocessor  12  to display the menu command screen shown in  FIG. 6  on display  20 . 
     The receipt of new messages is indicated by NEW MESSAGE textbox  65 . Data in textbox  65  is altered to indicate the quantity of new messages received. Further, an audible brief beep sound is generated by microprocessor  12  via audio circuitry  18  and speaker  21  when a new message data packet is received via datalink  32 . As new message are viewed, the data in textbox  65  is altered by microprocessor  12  to indicate how many messages remain to be viewed. 
     Audio messages may be recorded and attached to a message data packet or message record. When audio data is present in a message record, and that message is displayed that has an audio data record component, an audio indicator  81  resembling a speaker icon is shown on display  20 . Other audio message attachment indicators such as an audible beep (a two tone beep serves to distinguish an audio attachment from a single beep corresponding to a new message received), flashing display indicators or a text message indicating an audio data component for the present message record are also contemplated. It is also contemplated that audio messages are automatically reproduced on speaker  21  when a message data packet or record having an audio data component is displayed by the user of device  10 . 
     Operationally speaking, messaging device  10  will be described in accordance with the example message data shown in  FIG. 5 . In  FIG. 5 , the current message has been designated “For” James Smith as the recipient in accordance with the user selection thereof in listbox  50 . In reality, this the selection of James Smith is a selection of the telephone messaging device used by James Smith and the name corresponds to a unit logical identifier or network address used in transmitting data to devices connected to datalink  32 . Caller ID data is displayed automatically in textbox  52  in response to a telephone call detected by microprocessor  12  receiving data from caller ID electronics  26 . The caller&#39;s name is entered by the user in textbox  54  (if different from the name appearing in the caller ID textbox  52 ) and the caller&#39;s company name is entered in textbox  56  if different from the caller ID data. Current date/time of the call is recorded automatically by microprocessor  12  in textbox  58 . In the event the caller&#39;s telephone number differs from that shown in caller ID textbox  52 , another telephone number is entered in textbox  60 . As shown in the current example, checkboxes  66 ,  70  and  76  includes an “X” therein indicating the user has selected those predefined messages as they relate to the telephone call from Joe Salesman. A hand printed message is shown in message area  78 . When the message data packet defining all the data shown in the display screen of device  10  is transmitted to another telephone messaging device (identical to device  10 ) pushbutton  106  with a label of “Activate Reply Mode” is displayed or made active on the recipient device. 
     When activated, pushbutton  106  causes microprocessor  12  to split the message area  78  into two distinct areas, with the area designated  78 a identified as the “Reply” area. A hand printed, handwritten, or alphanumeric reply message is then entered at area  78 a by the recipient (here James Smith, identified in textbox  50 ). Tapping CLEAR pushbutton  85  will clear or erase handwriting or typed data entered into message area  78   a.  The messaging device  10  in use by the originator of the message (Receptionist) then receives command data from James Smith&#39;s messaging device to enter into a “real time” data transfer mode wherein the Receptionist&#39;s messaging device displays the reply message shown in  FIG. 5  in “real time”, that is, as data is entered by James Smith at his messaging device in area  78   a.  The message in area  78   a  will simultaneously be displayed on the originators messaging device and the recipient&#39;s messaging device in either graphical handwriting form or in the format of alphanumeric computer generated characters based on data entered via keyboard data entry. The “real time” reply mode provides a convenient mechanism for a person to immediately notify the sender of a message in regard to information that should be conveyed without delay. While the devices are in “real time” mode, the sender (here the “Receptionist”) may also enter additional data in the message area  78  and such input is immediately transmitted by microprocessor  12  to the second messaging device for immediate display. When the real time reply mode of operation is no longer needed, either party may activate pushbutton  107  to deactivate the reply mode and cease real time data exchange between the messaging devices. The real time data exchange mode is accomplished by microprocessor  12  continuously exchanging data between the two messaging devices via data communications interface electronics  30  and data link  32 . NEW MESSAGES textbox  65  now depicts that a new message has been received. Various checkboxes  68 ,  72   74  and pushbuttons  82 ,  84 ,  86 ,  88 ,  90   92 ,  92 ,  94   96 ,  98 ,  100 ,  102  and  104  are also shown in  FIG. 5 . 
     A person receiving a new message may desire to add further information to a received message on occasion, and the following describes the mechanism provided by device  10  for accomplishing such. Upon receiving a message at the recipients messaging device, the user may write or print in the message area  78  or tap pushbutton  80  to display the keyboard data entry screen and append additional message information into message area  78 . Microprocessor  12  appends keyboard or character data entered by the user below the existing message in area  78 . Additional message information such as “will send sample products” or “new source for product” are examples of additional text information a user may enter into message area  78 . Tapping the SAVE pushbutton after entering additional text in message area  78  instructs microprocessor  12  to save in memory  16  the additional message data in area  78  with the original message data record for the current displayed message. 
     Referring now to  FIG. 6 , a menu display screen for messaging device  10  that is displayed in response to activation of MENU pushbutton  104  is shown. In  FIG. 6  an array of pushbuttons corresponding to additional features or functionality provided by messaging device  10  are shown. SEARCH FOR NAME/NUMBER pushbutton  110  instructs microprocessor to display a search screen for previously saved or stored messages containing character strings. The search feature is described in detail below in association with  FIG. 8 . Pushbutton  112  activates the AUDIO record/playback screen shown in  FIG. 9  and described below. Pushbutton  114  provides a mechanism for archiving data. Activation of pushbutton  114  causes microprocessor  12  to transfer all message data records including message data packets, audio and reminder data packets to a removable compact flash memory card or to a personal computer via computer interface  24 . Pushbutton  116 , when activated, instructs microprocessor  12  to display a list of messaging devices that have been detected via device queries transmitted over data link  32 . The user is then provided with a list of known messaging devices from which the user of messaging device  10  may create groups or special lists of messaging devices. The definition of groups enables the user to select a group as the recipient of a particular message and upon activation of the SEND pushbutton  102 , a message is transmitted to all messaging devices listed in the group definition. Tapping pushbutton  118  signals microprocessor  12  to display “saved” message data packets. Saved messages are distinct from new or recently viewed message data packets (corresponding to entire messages) in that they are stored separately for future reference. When displaying saved message data packets or records, messaging device  10  presents the data in a format shown in  FIG. 2 . It is contemplated that a variety of alternative formats are conceivable for displaying information to a user of device  10 . Navigation pushbuttons  82 ,  84 ,  86  and  88  are used to navigate through the messages displayed. Pushbutton  120  SETUP DEVICE, when activated, instructs microprocessor  12  to enter into a setup mode wherein the user enters a name for the messaging device (which will be the identifier name that other messaging devices will know the device as) and the date/time setup. Other options available in the setup screen may include activation/deactivation of new message audio beeps. Also provided in the menu screen is an exit pushbutton  121 . Tapping EXIT pushbutton  121  causes messaging device  10  to return to a normal mode of operation as shown in  FIG. 2  or to mode of displaying message data packet information as in  FIG. 5  depending upon the display mode that was active prior to the activation of the menu pushbutton  104 . 
     Referring now to  FIG. 7 , a plurality of pushbuttons  122  are shown that correspond to a subset of the typical alphanumeric keys of a keyboard. Alphanumeric data is entered by the user via this screen configuration. A single tap of the stylus  36  on a character pushbutton causes the corresponding letter/number/symbol to appear in textbox  124 . Movement of the insertion point within textbox  124  is accomplished by the user tapping the cursor keys  126 . Upon completion of entering the desired data, the user taps pushbutton  128  (DONE) to complete entry of the data. The user may clear all the data in textbox  124  by tapping pushbutton  130  (CLEAR). The user may cancel the data entry mode by tapping the CANCEL pushbutton  132 . In all instances where the user may enter data into a textbox, it is contemplated that a simple stylus double-tap on any textbox discussed herein (such as textboxes  54 ,  56 ,  58  and  60  as well as messaging area  78 ) activates the alphanumeric data entry screen of  FIG. 7  for data entry. 
     Referring now to  FIG. 8 , a search screen for messaging device  10  is shown. The search feature is activated when a user taps pushbutton  110  in the menu screen of  FIG. 6 . The search screen includes a textbox  134  wherein a search string is entered by the user. After entering the alphanumeric search string data in textbox  134 , the user taps pushbutton  136  (SEARCH) and microprocessor  12  searches data records for messages containing the search string of textbox  134 . Microprocessor  12  searches all message data packets or message records and populates list box  138  with data from those message records. The search feature includes a search of Caller ID data, caller name data, company data, and telephone number data. Wild card characters such as “*” and “?” well known in the computer art are contemplated as recognized by microprocessor  12 . To display the entire saved message for any of those entries shown in listbox  138 , the user taps the desired entry in listbox  138  to “select” it and then taps the DISPLAY MSG pushbutton  140 . Alternatively, a single or double tap on any of the listed messages in listbox  138  instructs microprocessor  12  to display that particular message in the format of  FIG. 5 . When finished with the search feature, the user taps pushbutton  142  to exit the search screen and return to standard display of messaging device  10  (shown in  FIG. 2  or  FIG. 5 ). 
     Referring now to  FIG. 9 , the audio playback/record screen is shown. In this particular display screen, five audio functions are provided. Recording of audio messages is activated by tapping pushbutton  144 . Audio input via microphone  23  is digitized by audio circuitry  18  and microprocessor  12  and temporarily stored in memory by microprocessor  12 . A visual indicator (such as flashing on and off the text of the RECORD pushbutton) aids the user in knowing the record mode is activated. It is contemplated that audio messages will be limited in length in accordance with available unused memory storage in flash memory. Tapping the STOP pushbutton  146  halts the recording or playback process. Tapping the PLAYBACK AUDIO pushbutton  148  causes an audio message attached to a message data record to be played back via speaker  21 . Tapping the DELETE AUDIO FROM CURRENT MESSAGE pushbutton  150  causes audio data attached to a message data record to be deleted. SAVE AUDIO WITH CURRENT; MESSAGE AND EXIT pushbutton  152  causes the current digitized audio message data just recorded to be saved along with all other data for the currently active message data record. Also shown is EXIT/DONE pushbutton  154  which instructs microprocessor  12  to exit the playback/record audio mode of operation and return to the modes shown in  FIG. 2  or  5 . 
     Referring now to  FIG. 10 , another embodiment  160  of the present invention is shown. In this embodiment a messaging device  10  is fully integrated into a standard multiline telephone  162 . Such a combination of functionality conserves desktop space. 
     Referring now to  FIG. 11 , the main flowchart for the program executed by messaging device  10  is shown. At step  200 , on power up, the system is initialized. Initialization steps include: displaying the formatted display as shown in  FIG. 2 ; transmitting or broadcasting a device identification query message via data communications interface  30  to all other similar telephone messaging devices, any messaging devices receiving the device identification query respond by transmitting a data packet including their logical unit or device number and a name corresponding to the user of the device for entry in dropdown listbox  50 ; and initializing computer interface  24  and determining whether an interface with a personal computer is present and whether the keyboard of a local personal computer shall be used for alphanumeric data entry. It is contemplated that the underlying communications protocol used by device  10  periodically ascertains the existence of other devices connected to datalink  32  and updates the information in listbox  50  accordingly, much the same as the Windows operating systems implement the network “browse” functionality. Following step  200 , program execution continues at step  202 . At step  202 , microprocessor  12  checks for new caller ID data from caller ID electronics  26 . If new caller ID data is detected, program execution continues at step  204 . At step  204  a new telephone call is processed, data is entered by the user as required to fully define a new message data packet and the message data packet is sent to the desired recipient messaging device as selected by the user. Step  204  is described in more detail in the discussion of the flowchart of  FIG. 12 . Following step  204 , execution continues at step  206 . If at step  202  no new call has been detected, execution continues at step  206 . At step  206 , if user input has been detected by microprocessor  12 , step  208  is next executed. At step  208  user input is processed in accordance with the flowchart shown in  FIG. 13 . Following step  208  program execution proceeds to step  210 . If no user input is detected at step  206  then program execution continues at step  210 . At step  210  microprocessor  12  checks schedule data for reminder messages that have come due for display in accordance with reminder data packets previously stored. The details of step  210  are more fully described in relation to the discussion of flowchart of  FIG. 14  below. After step  210 , step  212  is executed and if any new message data packets are received from other telephone messaging devices then the message data packet is stored, the new messages counter displayed in textbox  65  is incremented and the message data packet is displayed in accordance with the format of  FIG. 5 . Optionally, the new message is stored and later displayed in response to activation of one of the message navigation command pushbuttons  82 ,  84 ,  86  or  88 . Following step  214 , execution returns to step  202 . If at step  212  a new message data packet has not been received, program execution returns to step  202 . It should be recognized that in the design of microprocessor based systems, receipt of communications and input data is normally interrupt driven. Input processing by messaging device  10  is shown in the  FIG. 11  flowchart form for ease of understanding the operation of the device. 
     Referring now to  FIG. 12 , a flowchart for the “Call Detected” step  204  of  FIG. 11  is shown. At step  220 , microprocessor  12  obtains caller ID data from caller ID electronics  26  including caller telephone number and caller name. Next at step  222 , microprocessor  12  initializes display  20  for input of data for a new message data packet as shown in  FIG. 2 . Caller ID data is automatically inserted in textbox  52 , date and time data is obtained from real time clock  14  and the date and time data are automatically inserted into textbox  58 . Next at step  224 , the user selects a recipient for the message from listbox  50 , enters additional name data in textbox  54 , enters company name data in text box  56 , additional telephone number information in textbox  60 , selects or checks predefined message checkboxes where appropriate (checkboxes  62 - 76 ) all described above in relation to  FIG. 2  and  FIG. 5 , and enters any custom or handwritten message desired in message area  78 . Next at step  226 , the user taps the SEND pushbutton  102  and microprocessor  12  creates a message data packet comprised of data from textboxes  52 ,  54 ,  56 ,  58 ,  60 , checkbox data from checkboxes  62 - 76  and any custom message data entered into message area  78  and transmits the message data packet to the messaging device (or devices in the event of a group definition in listbox  50 ) defined by the user selection in listbox  50 . Following step  226 , program execution returns to the calling routine. 
     Referring now to  FIG. 13 , a flowchart for processing user input corresponding to step  206  is shown in more detail. At step  230 , microprocessor  12  tests whether the input from the user is a navigation command input corresponding to activation of pushbuttons  82 ,  84 ,  86  or  88 . Such navigation pushbuttons instruct microprocessor  12  to display the message data packets for currently received or saved messages. Navigation pushbuttons include the next message pushbutton  82 , previous message pushbutton  84 , HOME pushbutton  86  and END pushbutton  88 . If a navigation input command is detected at step  230  then execution continues at step  232  and microprocessor  12  will display a new message data packet in accordance with the navigation input command. If the user input is not a navigation input at step  230 , then execution continues at step  234 . Following step  232  execution continues at step  234 . 
     If at step  234  the user input is activation of the CLR pushbutton  90 , then program execution continues at step  236  and the data displayed is cleared on display  20  and a blank input screen such as that shown in  FIG. 2  is displayed. After step  236  program execution continues at step  238 . If the CLR command is not received at step  234 , program execution continues at step  238 . If a DEL pushbutton  92  command is detected at step  238  then program execution proceeds with step  240  where the currently displayed message is cleared from the display and the corresponding message data packet for the message is deleted from memory by microprocessor  12 . Optionally, a “delete confirmation” message may be displayed requiring the user confirm the delete operation. Preferably, messaging device  10  would then display the next unviewed message if any message data packets are as yet unviewed by the user. If at step  238  the user input is not a DEL command, program execution continues at step  242 . After step  240 , execution continues at step  242 . If a SCHED pushbutton  96  command is detected at step  242 , program execution continues at step  244 . In step  244 , microprocessor  12  displays a scheduling data input screen and prompts the user to enter date/time and additional text message data to be displayed at the future date/time specified. The user enters such data and a reminder data record is created therefrom by microprocessor  12  and stored in flash memory  16 . After step  244 , execution continues at step  246 . If the user input at step  242  is not a SCHED command, execution continues at step  246 . 
     At step  246  user input is compared with the SAVE command or activation of pushbutton  96 , and if the command is detected, program execution continues at step  248 . At step  248 , the currently displayed message data packet on screen is permanently saved to flash memory as a “saved” message data packet (as opposed to temporarily stored message data packets received from any messaging devices). Alternatively, if the user has appended keyboard entered data or handwritten text in message area  78 , tapping the SAVE pushbutton  96  instructs microprocessor  12  to save the user modified data shown in message area  78  into memory  16  for the message currently displayed on display  20 , whether the message is a permanently saved or temporarily stored message data packet. Following step  248  execution continues at step  250 . If at step  246  the user input is not a SAVE command, execution continues at step  250 . At step  250 , if the user input is a SECURE command (pushbutton  100 ) then execution continues at step  252  and microprocessor  12  displays a password entry screen on display  20  wherein the user enters an alphanumeric password that is coupled with the message data packet for the currently displayed message, securing the current message from view by others. Subsequent attempts to display or delete a password protected message data record will require entry of the correct password before hand. After step  252 , execution continues at step  254 . If the user input is not a SECURE command at step  250 , execution continues at step  254 . 
     If at step  254  the user input command is identified as a SEND command corresponding to the user tapping pushbutton  102 , execution proceeds to step  256 . At step  256 , microprocessor  12  creates a message data packet comprised of all data input by the user in the various textboxes and checkboxes, message data from the message area  78 , caller ID data, and date/time data and transmits the message data packet to the messaging device identified by the recipient identifier data in listbox  50 . Again, the recipient identifier may be a group of messaging devices. After step  256 , execution continues at step  258 . If at step  254  the user input is not a SEND command, execution continues at step  258 . If at step  258  the user input command is a MENU command (pushbutton  104 ) then execution continues at step  260 . If the MENU command is not detected at step  258  execution continues at step  262 . At step  260 , microprocessor  12  displays the menu of additional commands and features shown in  FIG. 6 . Following step  260  execution continues at step  262 . 
     At step  262  if the user input indicates that the user has tapped one of the checkboxes ( 62 - 76 ) then the display is updated to toggle or invert the state of the checkbox and corresponding data is updated in memory. Following step  264  execution continues at step  266 . If the user input at step  262  is not a “checkbox ticked” command then execution continues at step  266 . If a Reply Mode command is detected at step  266  then execution continues at step  268  wherein the current reply mode state of operation is inverted, either entering or exiting reply mode of operation discussed above. For example, if the reply mode is currently active then the reply mode is deactivated, and vice versa. Following step  268  execution continues at step  270 . At step  270  if the user is inputting data into a textbox or message area  78  or  78   a,  then program execution continues at step  272  and microprocessor  12  updates the display  20  accordingly. For example, user input data via the alphanumeric data entry screen of  FIG. 7  is processed here for entry of data into the textboxes of  FIG. 2 . Further, if the reply mode is active, user input data entered in message area  78  or  78   a  is transmitted to a messaging device currently engaged in reply mode operation with messaging device  10 . If a user is viewing a previously received message and desires to add further comments or notes to the message in area  78 , additional message information input is received by microprocessor  12  via touch sensitive overlay  22  and is appended into area  78  at step  272 . Following step  272  execution returns to the calling routine. If at step  270  the user input is not textbox or message area data, then execution returns to the calling routine. 
     Referring now to  FIG. 14 , a flowchart for step  210  of  FIG. 11  is shown. At step  280  microprocessor  12  obtains the current date/time from real time clock  14 . Next at step  282  microprocessor  12  compares the current date/time with the date/time data in previously stored reminder data packets or records to ascertain whether any of the reminders have come due. Next at step  284 , those reminder data packets that are due for display are displayed on display  20  (in serial fashion if more than one reminder is detected as due). Next at step  286  the user is prompted via a displayed message to cancel or reschedule the reminder. If the user wishes to reschedule the reminder, execution continues at step  288  and microprocessor  12  inputs new reminder date/time data from the user for the reminder data record currently of interest. If at step  286  the user response is to not reschedule the reminder message, then the reminder data record is deleted at step  290 . Following both step  290  and step  288 , execution returns. 
     Referring now to  FIG. 15 , a flowchart is shown for step  260  of  FIG. 13  wherein the system MENU is displayed in response to the user tapping or activating pushbutton  104 . The display  20  appears as is shown in  FIG. 6  at this time. All user inputs discussed in regard to  FIG. 15  are with respect to functions available in the MENU screen. If the input from the user at step  300  is an activation of pushbutton  110  the “Search For Name/Number” command, then execution continues at step  302 . The search screen shown in  FIG. 9  is displayed at step  302  and provides a mechanism for the user to enter alphanumeric search strings and find all stored message data packets containing the search string of interest. The operation of the search feature is also described above in regard to the discussion of  FIG. 8 . After step  302 , program execution continues at step  304 . If the user input command is activation of the Record Audio pushbutton  112 , execution continues at step  306  and microprocessor  12  changes display  20  so that the Playback/Record Audio screen of  FIG. 9  is shown. The commands available in the Playback/Record Audio screen are discussed above and enable the user to record, playback or delete an existing audio message. After step  306 , execution continues at step  308 . If the user input command is not pushbutton  112  at step  304 , execution continues at step  308  thereafter. If at step  308  the user command is activation of pushbutton  114 , then execution continues at step  310  where the user is prompted to activate the process of transferring saved message data packets to a removable compact flash memory device inserted into slot  46  of device  10  (see  FIG. 3 ) or activating a transfer of stored message data packets to a personal computer via computer interface  24  for archiving data. Optionally, data archived on a removable compact flash memory card or on a personal computer may be restored or recovered to the flash memory of messaging device  10  in accordance with user input commands to restore data. Following step  310  execution continues at step  312 . If at step  308  the user input was not an archive data command, execution continues thereafter at step  312 . 
     At step  312  if the user input is pushbutton  116  (Create Recipient Group command) execution continues at step  314 . At step  314 , microprocessor  12  displays a listbox containing entries for all messaging devices detected since power up of messaging device  10 . The user inputs an alphanumeric name of a new group and adds one or more detected messaging devices from the listbox to the newly created group. For example, those persons using a messaging device in marketing may be added to a new group named “marketing” so that any messages data packets sent to “marketing” are delivered to a group of recipients. New group definitions are stored in flash memory  16  and appear in listbox  50  as a potential message recipient. After step  314 , execution continues at step  316 . If at step  312  the user input is not a pushbutton  116  command input, then execution continues at step  316 . If at step  316  the user input is pushbutton  118 , the View Saved Messages option, then execution continues at step  318  and microprocessor  12  causes display  20  to display permanently saved message records saved via activation of the SAVE pushbutton  96 . Saved messages are distinct from recently received or viewed messages as such are stored permanently for later recall, whereas new messages are not stored in the same area of memory. This scheme creates two groups of stored message data packets, permanently saved message records and new unviewed and/or viewed messages records that have not been “saved” via activation of pushbutton  96 . The navigation pushbuttons  82 ,  84 ,  86  and  88  provide the user with a means to view the various saved message records. It is contemplated that the user activates the CLR pushbutton  90  to exit the viewing of saved message data packets mode and return messaging device  10  to the MENU screen of  FIG. 6 . After step  318 , execution continues at step  320 . If at step  316  the user input is not pushbutton  118 , execution continues at step  320 . At step  320  if the user has activated the Setup Device pushbutton  120 , then execution continues at step  322  and the user is prompted by microprocessor  12  via display  20  to enter setup information including the device name (for example “John Doe”) corresponding to the users name, and inputting current date/time data for use in initializing real time clock  14  to the current date/time. If the user changes the device name, messaging device  10  broadcasts this information via datalink  32  to all other messaging devices to update their logical unit and corresponding unit name data records. After step  322 , execution continues at step  324 . If the Exit Menu pushbutton  121  is activated by the user at step  324  then execution returns to the calling routine, otherwise execution continues at step  300 . Upon return from the MENU mode of  FIG. 6 , messaging device returns to the mode of displaying the last displayed message prior to entering the MENU mode of operation. 
     While the invention has been illustrated and described in detail in the drawings and foregoing description of the preferred embodiment, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
