ABSTRACT:
This disclosure relates to a multi-function telephone apparatus and a control method therefor. When an application program (hereinafter referred to as program) stored in an IC card is executed, a state of the program execution and an incoming/outgoing call are supervised. It is controlled in a way that the execution of the program is automatically suppressed at the time of incoming/outgoing call and restarted from the point it was suppressed when the telephone was completed. Further, when the terminal emulation program stored in the IC card emulates the telephone apparatus as a terminal of the host system, the communication with the host is efficiently executed with reduction of the line load.
