CLAIM OF PRIORITY 
   This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application entitled Method for Controlling Fax Data Transmission According to the Printing Method of Receiver earlier filed in the Korean Industrial Property Office on 14 Jul. 1999, and there duly assigned Serial No. 99-28465 by that Office. 
   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This invention relates to a method for controlling transmission of facsimile data. More specifically, the invention relates to a method for transmitting facsimile data from a memory of a transmitting part facsimile to a receiving part facsimile in order or in reversed order according to a facsimile data receiving and outputting way of the receiving part facsimile. 
   2. Description of the Related Art 
   Generally, a facsimile is a machine for exchanging documents. In the facsimile, a scanner for scanning a document, a printer for outputting data in the shape of letters, and a communication unit for transmitting and/or receiving data to and/or from another part in wide area are integrally formed. Such a facsimile includes a variety of additional functions to meet demands of users. As one of the additional functions, facsimile data is scanned and stored in a memory before being transmitted. The facsimile data scanned and stored in the memory is advance-transmitted from a transmitting part facsimile to a receiving part facsimile in order from the first page regardless of the facsimile (fax) data outputting way of the receiving part facsimile. At this time, the receiving part needs to realign the fax data on every reception of the fax data. 
   Exemplars of the art, U.S. Pat. No. 5,877,870 for Image Transmission Control Method for Facsimile Apparatus issued to Sakai, U.S. Pat. No. 5,515,177 for Facsimile Data Transmission over a Low Rate Network by One Dimensional Decoding and Two Dimensional Re-encoding issued to Propach et al., U.S. Pat. No. 4,661,857 for Facsimile Communication Control Method issued to Kondo, U.S. Pat. No. 6,040,922 for Devices and Method for Facsimile and Data Communication issued to Umeda et al., U.S. Pat.

No. 5,796,493 for Facsimile Machine issued to Murai et al. disclose the data transmission for a facsimile device. 
   I have found that conventional art does not properly show an efficient way for the receiving part facsimile to avoid reordering the facsimile data on every reception. 
   SUMMARY OF THE INVENTION 
   It is therefore an object of the present invention to provide a method for transmitting fax data stored in the memory of the transmitting part facsimile to the receiving part facsimile according to the fax data outputting way of the receiving part facsimile. 
   It is another object to have a more efficient method of organizing facsimile data for printing on a receiving part facsimile. 
   It is yet another object to have a method supporting a non-standard mode while avoiding the receiving part to realign the fax data on every reception of the fax data. 
   It is another object to have a system that will give a visual feedback to the user on the transmitting part facsimile about the ordering method of the data set by the receiving part facsimile. 
   The above and other objects are provided according to the present invention by providing a method for controlling transmission of fax data as described hereinafter. A document to be transmitted from a transmitting part facsimile to a receiving part facsimile is scanned and stored. When the document is completely scanned, a pre-entered telephone number of the receiving part is dialed. After the receiving part telephone number is dialed, a data outputting way is required and received from the receiving part facsimile, in the case that a call for transmitting document data is fixed between the transmitting part facsimile and the receiving part facsimile. Then the document data stored according to the received data outputting way is transmitted. 
   Preferably, the method for controlling transmission of fax data further includes the step of displaying the data outputting way of the receiving part facsimile received from the receiving part facsimile. The data outputting way applied to the present invention may be one of a face down way in which the stored document data is output in order from the first page of the stored document data; and a face up way in which the stored document data is output in reversed order from the last page of the stored document data. 
   In addition, according to the present invention, both of the transmitting part facsimile and the receiving part facsimile support a non-standard mode and report the data outputting way by fixing a data outputting way mode bit. Moreover, the scanned document data is managed in the unit of pages and stored in the memory.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Turning now to the drawings, as shown in  FIG. 1 , a transmitting part facsimile  100  is connected to a receiving part facsimile  200  by means of a communication net so that data can be exchanged between the facsimiles  100  and  200 . 
   Referring to  FIG. 2 , a controller  110  generally controls the transmitting part facsimile  100  according to a system program that is fixed in a memory  150  to operate the facsimile  100 . In addition, the controller  110  controls a method for transmitting fax data stored in the memory  150  to the receiving part facsimile  200  corresponding to a fax data outputting way transmitted from the receiving part facsimile  200 . 
   In the memory  150 , the system program for operating the transmitting part facsimile  100 , and contents related to transmission and reception of protocol data and letter data are stored. According to the present invention, pre-scanned document data to be advance-transmitted is stored in the memory  150  and transmitted to the receiving part facsimile  200  by a transmission signal from the controller  110 . 
   An operational panel (OPE)  170  includes, as shown in  FIG. 5 , a plurality of keys  172  and  173  for generating key data of the transmitting part facsimile  100 . When generated, the key data is input into the controller  110 . The OPE  170  further includes a displaying unit  171  for displaying the processed state of various operations of the controller  110  and display data such as system information. In addition, according to the present invention, the data outputting way of the receiving part facsimile  200  which is transmitted from the receiving part facsimile  200  is displayed on the displaying unit  171 . 
   A scanner  160  scans data of the document, converts the scanned data into digital image data, and supplies the controller  110  with the converted digital image data. A modem  120  modulates and outputs output data of the controller  110  into analog form and demodulates and outputs analog input signals by control of the controller  110 . 
   A network control unit (NCU)  130  is operated to form a communication loop of a public switching telephone network (PSTN) formed of a ring and a tip and interface signals of the modem  120  and the PSTN by control of the controller  110 . A printer  140  outputs print data stored in the memory  150  by a print signal from the controller  110 . 
   Referring to  FIG. 3 , Phase A is a sequence of fixing a call and establishing a communication line. In the case of a manual operation, the transmitter dials the telephone number of the receiving part under the off-hook state, senses the bell sound of 16 Hz from the receiving part subscriber, checks whether the receiving part is hooked off, and connects the facsimile to the communication line when it is checked that the receiving part is hooked off. In the case of an automatic operation, when the facsimile is connected to the communication line and the receiving part facsimile is in a fax mode, a 1100 Hz tone is transmitted from the transmitting part to the receiving part for 0.5 second at an interval of 3 seconds until the receiving part responds. At this time, the receiving part transmits a 2100 Hz tone for 2.6 to 4 seconds. The receiving part transmits the called equipment discrimination signal (CED). 
   Phase B is a sequence of checking the states of a terminal and a transmission line and controlling the terminal. In Phase B, the transmitting and receiving standby states of the terminal, display and determination of a terminal constant and synchronizing state are checked and a fax message is prepared to be transmitted. 
   Phase C is divided into Phase C 1  for control during message transmission and Phase C 2  for transmission of the fax message. In other words, Phase C is a sequence of transmitting the message, checking the message transmission, and maintaining synchronism. 
   Phase D is a sequence of terminating the message and terminating reception and so on. The disconnection command signal (DCN) would be sent by the transmitting part to the receiving part. In the case of continuous transmission, Phase D is followed by Phase B or Phase C to repeat the transmitting sequence. 
   In addition, signals used in the protocols as shown in  FIG. 3  will be described hereinafter. Non-standard facilities (NSF) is used to discriminate demands of a specific user that cannot be covered by T recommendation. ITU-T (International Telecommunications Union) recommendation sets a protocol for facsimile calls. Called subscriber identification (CSI) is used to supply a specific discriminating member of a subscriber of a receiving part by an international telephone number. Digital identification signal (DIS) specifies a standard CCITT (Consultive Committee International Telegraph and Telephone) capability of the receiving part equipment. 
   In addition, non-standard facilities set-up (NSS) is a digital command responding to information included in an NSF signal. Transmitting subscriber identification (TSI) reports that the continuous information is the discriminating member of the transmitting part, and supplies facsimile procedure with additional security information. Digital command signal (DCS) is a digital setup command responding to a standard capacity checked by the DIS signal. 
   Confirmation to receive (CFR) is a digital response confirming that the entire previous message procedure is completed and the message transmission starts. End of procedure (EOP) is a response that the message transmission is completed. In addition, message confirmation (MCF) reports that the entire message is satisfactorily received and displays whether an additional message exists or not. 
   Referring to  FIGS. 1 to 5 , the method for controlling transmission of fax data according to the outputting way of the receiving part of the present invention will be described hereinafter. 
   First, an advance-transmitting function is selected. Then, the telephone number of the receiving part facsimile  200  is input using the number and letter generating unit  172  of the OPE  170  as shown in  FIGS. 2 and 5  (S 50 ). In order to transmit fax data from the transmitting part facsimile  100  to the receiving part facsimile  200 , a document is scanned and stored in the memory  150  (S 100 ). When the document is completely scanned, the controller  110  dials the pre-inputted telephone number of the receiving part facsimile  200  to transmit the data stored in the memory  150  (S 200 ). After the telephone number is dialed, it is determined whether a call for exchanging fax data between the transmitting part facsimile  100  and the receiving part facsimile  200  is connected or not (S 300 ). 
   The determination as to whether the call is connected can be checked through predetermined protocol exchanges after a dialing signal is received from the controller  110  shown in  FIG. 2  to the receiving part facsimile  200 . If it is determined that the call for exchanging the fax data between the transmitting part facsimile  100  and the receiving part facsimile  200  is formed, the transmitting part requires the fax data outputting way of the receiving part facsimile  200  (S 400 ). 
   The requirement of the fax data outputting way is performed in Phase B that is a sequence of generally checking the states of the facsimile and the transmission line and controlling the facsimile among the protocols used for transmission and reception of the fax data as shown in  FIG. 3 . As described above, in Phase B, the facsimile transmission and reception standby state and synchronization state are checked and the fax message is prepared to be transmitted. In other words, the transmitting part facsimile  100  requires the fax data outputting way applied to the receiving part facsimile  200  to be reported in Phase B. 
   According to a preferred embodiment of the present invention, T.30 protocol is applied to transmission and reception. In the case that the transmitting part and the receiving part respectively support a non-standard mode, the receiving part reports the fax data outputting way through a prefixed (predetermined) fax data outputting way mode bit. 
   When required to report the fax data outputting way, the receiving part facsimile  200  transmits a presently applied fax data outputting way to the transmitting part facsimile  100  (S 500 ). 
   Receiving the fax data outputting way of the receiving part facsimile  200 , the transmitting part facsimile  100  displays the received fax data outputting way on the displaying unit  171  of the OPE  170  as shown in  FIG. 5  (S 600 ). After the fax data outputting way is displayed, the fax data stored in the memory  150  is transmitted to the receiving part facsimile  200  according to the displayed fax data outputting way (S 700 ). 
   The fax data outputting way of the receiving part facsimile  200  applied to the present invention is one of a face down way in which document data stored in the memory  150  is output in order from the first page thereof and a face up way in which document data is output in reversed order from the last page thereof. 
   Step S 700  will be described more in detail. After the fax data outputting way is displayed at step S 600 , it is determined whether the fax data outputting way is the face down way or not (S 710 ). If it is determined that the fax data outputting way is the face down way, the document data stored in the memory  150  is transmitted to the receiving part facsimile  200  in order from the first page of the document data (S 720 ). Otherwise, if it is determined that the fax data outputting way is the face up way, the document data stored in the memory  150  is transmitted to the receiving part facsimile  200  in reversed order from the last page of the document data (S 730 ). 
   As described above, the present invention divides and stores the fax data into units of pages and transmits the fax data in order or in reversed order according to the fax data outputting way of the receiving part when the fax data is advance-transmitted in the memory. Accordingly, the fax data does not need to be realigned when received which results in an enhanced convenience. 
   This invention has been described above with reference to the aforementioned embodiments. It is evident, however, that may alternatives, modifications and variations will be apparent to those having skill in the art in light of the foregoing description. Accordingly, the present invention embraces all such alternatives, modifications and variations as fall within the spirit and scope of the appended claims and their equivalents.
