Description:
STATEMENT OF GOVERNMENT INTEREST 
     The invention described herein may be manufactured and used by or for the government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor. 
    
    
     BACKGROUND OF THE INVENTION 
     (1) Field of the Invention 
     This invention generally relates to an automatic message filing system. More particularly, the invention relates to an automatic message filing system in which message traffic received via a submarine broadcast or the like is processed for display and long term storage. 
     (2) Description of the Prior Art 
     In present submarine communication systems, incoming data is routed from a receiver to a teletype (TTY). As data is received, the TTY prints and stores this data in memory. The TTY&#39;s memory is limited and will eventually replace old data with new data received. Therefore, the current system does not support long term message file storage. Instead, files are printed from the TTY and these paper copies are stored in a very limited space. 
     There are various makeshift equipment lineups and modifications currently in the fleet that make this process somewhat automated. There does not appear, however, to be any written standard configuration that documents the equipment, wiring configurations, material required or describe the software functionality to automatically process naval messages in a computer for future use and long term storage. The Automated Message Filing System (AMFS) of the present invention would resolve this long term file storage problem while providing a very efficient method of handling Naval messages. 
     Thus, earlier systems were not available for the intended purpose of the present invention and therefor do not address the difficulties identified above. 
     The following patents, for example, disclose the use of teletype machines and in some instances a computer, but do not disclose a combined system including a teletype machine linked to a computer via a converter so as to enable retrieval, dissemination and/or long term storage of data.

     Kuseski discloses a data communications apparatus with storing and forwarding of text. The device is not specific as to radio teletype. 
     Christensen e t al. disclose a teleprinter terminal with plural microprocessors. The device, however, does not appear to describe storing and forwarding of messages. 
     Morecerf et al. disclose a shipboard system with plural transmitters and receivers connected to computer and teletype units. Distribution of messages from a teletype to a computer is not disclosed. 
     Loskorn discloses a line adaptor for data communication and appears to discuss only temporary buffering, not long term storage. 
     It should be understood that the present invention would in fact enhance the functionality of the above patents by networking the teletype device with a computer via a converter thereby providing a simplified and structurally sound system. 
     SUMMARY OF THE INVENTION

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     In general, the present invention is directed to an automated message filing system in which incoming messages are downloaded off of a teletype machine and input into a computer. A reverse situation is also available whereby the computer is able to supply an approved outgoing message to the teletype machine for dissemination. 
     Advantages of the inventive automated message filing system include the ability to implement a paperless message management system on board a ship or in any comparable situation where incoming messages are intercepted by a teletype machine and outgoing messages are sent by a teletype machine. The method will dramatically increase the efficiency of shipboard and other similar communications. In addition, the method is very inexpensive to implement due to utilization of current shipboard equipment including the teletype and computer. 
     Referring now to FIGS. 1 and 2, the automated message filing system is best illustrated by the use of block diagrams as shown and includes a teletype machine  10  and a computer  12  with a monitor  14  as basic components of the system. In order to convert data received by the teletype machine  10  into compatible data for the computer  12 , a converter  16  is disposed to receive data from the teletype machine  10  and convert the data prior to input into the computer  12 . 
     By way of example, the computer  12  is shown as an IBM compatible computer which utilizes a Windows &#39;95 or Windows 3.1 operating system, as manufactured by Microsoft Corporation. The converter  16  is shown as an RS232/MIL 188C converter. The selection of the converter is intended to be compatible to the teletype machine  10  being used, in this instance, the teletype machine  10  processes a MIL-STD-188C signal, thus requiring selection of a compatible converter. In the development of computer software, hardware, teletype machinery, and the like, it should be understood that variations and modifications may be made to the equipment illustrated herein and those advancements in the industry are intended to be included within the scope of this invention. 
     The basic signal flow for the automated message filing system is shown in detail in FIG.  1 . In particular, incoming data, represented by solid lines, is received by the teletype machine  10 . The teletype machine  10  includes a message forward (MSG FWD) function which automatically routes data to the converter  16 . At the converter  16 , the MIL-188C signal is converted to a RS232C signal and then routed to a port on the rear of the computer  12 . The particular connections will be described in further detail in association with FIG.  3 . 
     Outgoing data, represented by dotted lines, is sent from computer  12  to converter  16  where the RS232C signal is converted to a MIL-188C signal. The signal is then routed to teletype machine  10  for transmission. At the time of receiving incoming data or as data is retreived from computer  12  for transmission, the computer  12  displays the data on monitor  14 . 
     Referring now in detail to the flow diagram of FIG. 2, the sequence of events is best described as a series of steps shown in FIG. 2, though the diagram is not of a conventional flow chart model. Any data in the form of files can be retrieved at step  100  for printing, copying, transmission, deletion, or other file management functions. Data being processed for transmission is passed to the teletype at step  110  and data may also be stored for later use or long term storage at step  120 . 
     A primary purpose, of course is the automated processing of an incoming message. In that instance, the data is received into the teletype machine  10  at step  110 . The software of the computer  12  detects incoming data at step  130 . The data received by the computer  12  at step  130  may either be directly displayed on the computer monitor  14  at step  140 , scanned for pertinent message data at step  150  or both displayed and scanned. Once the messages have been displayed and/or scanned, the incoming data is sorted into appropriate files at step  160  and forwarded to step  100  for performance of file management functions such as storage at step  120 . As shown in the diagram, the incoming message or data can also be immediately stored as data files at step  110  without processing the same through the software at steps  130  through  160 . 
     In addition to the receive function, the automated message filing system is capable of transmitting data, represented by the dotted lines in FIG.  1 . When an outgoing message has been completed, a radio operator can use the file management function of the software of the computer  12  at step  100  to extract an ASCII formatted message from a disk, and route the signal to the desired teletype machine  10  via the converter  16 . When the message is in the teletype machine  10 , the message can then be routed by conventional means to a transmitter (not shown) for transmission. 
     Referring now to the hardware wiring diagram of FIG. 3, the teletype machine  10  processes an MIL-STD-188C signal as explained. Teletype  10  has DB25 female connector  18  which, in the prior art, would be connected directly to DB25 male I/O connector  20 . Connector  18  supports two data ports. Port  1  allows for normal I/O connection and Port  2  allows for message forwarding, e.g., forwarding messages to or from another teletype. To implement the current invention, Y-cable  22  is inserted between connectors  18  and  20 . Y-cable  22  has mating connectors  22   a  and  22   b  which mate with connectors  18  and  20 , respectively. Leg  22   c  of Y-cable  22  connects Port  1  to I/O connector  20 . Leg  22   d  of Y-cable  22  connects Port  2  to converter  16  first I/O connector  16   a  via third mating connector  22   e . Computer  12  connects to second I/O connector  16   b  of converter  16 . 
     The teletype machine  10  processes incoming data from a receiver via TTY Port  1 . Using the TTY&#39;s message forward (MSG FWD) function, the incoming data is sent out TTY Port  2 , and then routed through the converter  16  to change the MIL-188C signal to RS232C. The computer  12  receives the RS232C signal where it is processed by the software. 
     The software monitors each character as it is received by the computer  12  for specific information pertinent to naval messages, i.e., Start of Message (SOM), End of Message (EOM) and Classification. The computer will then file all messages classified as SECRET and below to a hard disk. If a TOP SECRET message is detected, the software user is prompted to delete it or save it to a floppy diskette. 
     The messages that are saved can be retrieved for printing, deleting, viewing, electronic copying to diskette, and other file manipulation functions well known in the computer art. If there is a network available, the messages can be placed on a network for paperless dissemination of the message files. 
     There is also the capability to electronically transfer ASCII formatted outgoing messages from the computer  12  to teletype machine  10 . Messages that are to be transmitted from the ship can be drafted on a computer, routed for editing on a diskette or LAN, transferred from the computer  12  to the teletype machine  10  via the converter  16  and transmitted. This capability is a very efficient way of preparing messages for transmission and dissemination since word processing software, standard with typical computers, can be used to draft the messages. 
     Accordingly, as the incoming data (represented by solid lines in FIG. 1) is received by the teletype machine  10 , using the teletype machine  10 &#39;s message forward function, the data is automatically routed to the converter  16  where the MIL-188C signal is converted to RS232C and then routed to the computer  12 . At this point the software detects the incoming data and displays it on the computer monitor. When the end of message (EOM) is detected, the software automatically files this message to the computers hard disk. In addition to the receive function, the automated message filing system is also capable of transmitting data (represented by dotted lines as shown in FIG.  1 ). When an outgoing message has been approved for release by the Commanding Officer, the radio operator can use the software to extract the ASCII formatted message from disk, route the signal to the desired TTY via the RS232C, to the MIL-88C converter. When the message is in the TTY, the message can then be routed by conventional means to a transmitter for transmission. 
     An advantage of the invention is the ability to simplify dissemination and storage of data incoming over a teletype machine, in whatever environment the teletype machine is used. 
     By the present invention, automated message retrieval in a paperless environment with extended storage capabilities is conducted in a manner not previously conceived in the art, and as a result the system has a wide range of uses and implementation potential. In particular, it should be appreciated that the invention need not be limited to shipboard use, but may be used in virtually any environment where there is a teletype machine, converter, and computer available for linking as described. The disclosure directed to the Navy and shipboard use is by way of example only. 
     This invention has been disclosed in terms of certain embodiments. It will be apparent that many modifications can be made to the disclosed system and apparatus without departing from the invention. Therefore, it is the intent of the appended claims to cover all such variations and modifications as come within the true spirit and scope of this invention.
