Performs control when transmission and reception data are code data in the BFT mode. The image data processing application 15 performs processing and control in the case where the transmission and reception data are code data in the BFT mode but there is no corresponding application but image data.

FIG. 3 is a diagram showing a data format of the code data. FIG. 7A shows image information data (within a page) at the time of code data transfer. Unlike ordinary G3 FAX data, the image information data is divided into two parts, and data information is added as frame information at the beginning. The data area is a code data area defined by the frame information.

FIG. 1B shows frame information. The frame information includes various control information (various control and management information of a transmission source), a data type (code data, image data),
It consists of a compatible application name (processable application name), creation date and data size.

The operation of the first embodiment according to the present invention will be described. In the HD storage device 7, general-purpose file data created by the general-purpose application 16 is stored. When this file is transmitted to the partner receiver, the code data processing application 1
In step 4, a frame is created in the transmission data, and a transmission file is read and created in the data. After the transmission data is created, the transmission data and the destination information are transmitted to the communication control unit 12.
Hand over to The communication control unit 12 uses the CCU according to the destination information.
The control unit 21 is instructed to start communication.

Dialing is performed by the CCU control unit 21, and after a line is connected to the partner device, a protocol is transferred according to an instruction from the communication control unit 12. After the communication connection, when the DIS frame is notified from the receiver, the frame is analyzed, and if the capability of the partner receiver side is capable of receiving the BFT mode, the DCS frame is immediately replied, and then the transfer of the file data is instructed. .
