Abstract

PURPOSE:To reducd the load of the host processor in case the communication control unit receives the transmission of message and the answer reception command from the host processor, by transmitting the answer urge command with no interruption given to the host processor. CONSTITUTION:When host processor 1 gives the command for the transmission of message and the answer reception, communication control unit 2 executes this command. And in case no answer is received even after the prescribed time, unit 2 is set into the urged character transmission mode to transmit the urged characters autonomoualy. Thus the processes decided previously can be executed without any indication of the host processor to reduce the load of the host processor.
