ABSTRACT:
In the case where a data terminal is connected to a portable communicating apparatus and a data communication is executed, it is intended to properly switch the data communication and a speech communication in response to an incoming signal. In a handyphone, when the incoming signal is received from a wireless line, when a CNG signal or a silent state is detected by a CNG silent detection circuit, a control unit allows an activation signal generation circuit to generate an activation signal. When the activation signal is detected by an activation signal detection circuit of a facsimile terminal, the control unit outputs a first response signal to the handyphone and executes a facsimile reception. After the end of the facsimile reception, the control unit allows the handyphone to output a second response signal indicative of the end of the facsimile reception. When the second response signal is detected, the control unit of the handyphone releases the wireless line.
