いる。FIG. 2 is a flow chart showing the operation of the embodiment of the present invention. This procedure is stored in the memory 2 in advance as firmware, and this firmware processes according to the CPU 1 to enable full-duplex communication. There is.
【０００９】先ず、ステップ２１では送信データの有無
を判定しており、送信データの待機を行っている。送信
データがあれば、この送信データは送信先アドレスと共
に例えば送受信ポート３へ一時格納される。First, in step 21, the presence or absence of transmission data is determined, and the transmission data is on standby. If there is transmission data, this transmission data is temporarily stored in, for example, the transmission / reception port 3 together with the transmission destination address.

行われる。In response to the presence of the transmission data, step 2
At 2, it is determined whether the mode is the full-duplex communication mode. This determination is made based on whether or not the operator has instructed the full-duplex communication mode due to a switch or the like. If not full-duplex communication, normal half-duplex communication mode communication is performed in step 23.

Then, it is determined whether or not there is a call addressed to itself from the destination facsimile machine. When there is a call addressed to itself, the transmission destination address stored in the transmission / reception port 3 is compared with the transmission source address of this call.

手の通信モードが識別できることになる。If a match is detected, step 25 detects if the other device is in full-duplex communication mode.
In this case, if a flag indicating whether the own device selects the full-duplex communication mode or the half-duplex communication mode is transmitted to each other in advance during the communication sequence as the pre-processing of data transmission, this flag By determining, the communication mode of the other party can be identified.

る。If the other party is also in the full-duplex communication mode, full-duplex communication is performed in step 26. At this time, the port 3 performs the transmission process and the port 4 performs the reception process. Of course, the partner device is also performing full-duplex communication at this time.

通信モードのままであることは勿論である。When the full-duplex communication is completed in steps 27 and 28, a communication end processing step 29 is performed. Of course, as shown in steps 24 and 30, if there is no incoming call from the partner device during transmission and before the end of transmission, the half-duplex communication mode remains as in step 31.

いう効果がある。As described above, according to the present invention, when there is an incoming call from the other party, the transmission and the reception are performed at the same time, so that the full-duplex communication line can be effectively used. Therefore, there is an effect that the communication cost can be reduced.
