Abstract

PURPOSE: To make it possible to control a system without specifying the other-party information unit for calling, by transmitting a transmission request signal to the other party station and by transmitting transmission data after receiving a transmission permission signal from the other party station.
CONSTITUTION: In the data processing network system operated by providing a timer circuit which is started when calling is received, outgoing and incoming call control part 9A accepts an incoming call and transmission/receiving control part 8A starts timer 10A in case that the call comes to A station 2A. When carrier signal CD rises from the other party station in the course of time counting of timer 10A, control part 8A detects it to reset timer 10A and decides the other party station as the primary station to receive data. Meanwhile, timer 10A transmits time-out signal TO, and control part 8A transmits transmission request signal RS to the other party station, and the other party station accepts this signal to transmit transmission permission signal CS to A station 2A, and A station 2A transmits transmission data to the other party station. Thus, the system can be controlled without specifying the other-party information unit for calling.
