PURPOSE:To simplify an application program by informing contents of an identification signal received from an opposite party and discriminated to be effective by a communication controller to a personal computer or a word processor at the procesure of the connection. CONSTITUTION:In receiving a CNR (call) command 1 from a personal computer, an automatic call 2 is applied to call an opposite FAX and when a telephone network is connected to the opposite FAX, an RNC (connection confirmation) command 3 is sent to the personal computer to send a CNG (call tone) signal 4. In receiving a DIS (digital identification) signal 15 from an opposite signal, the contents are discriminated and when the contents are effective, an LRA (called terminal equipment not confirmed) command is sent to the personal computer. In receiving the DIS signal in this way, the communication controller informs the contents to the personal computer or the word processor when the contents are effective. Thus, since the personal computer or the word processor has only to await the LRA command, the application program is not complicated.
