Abstract
PURPOSE: To make it possible to offer services to several communication circuits by using the data input control part of an arithmetic controller in common among several communication controllers, by providing a control memory unit, and by attaining this assignment by an alternation switch.
CONSTITUTION: To send out character information via input-output channels SIO for series-parallel or parallel series conversion, the arithmetic controller when a transmitted machine number agrees with one of SIOs of the communication controller sets address FFAD by decoder circuit DCD and the SIO channel number is set into address register AR and stored in memory M. Through the control of control circuit CNT, the character information from the input-output bus is parallel/series- converted via corresponding SIO and then sent out. At the reception time, the information passes through the reverse path, and the output of control memory CS is selected by SW to exercise the error inspection of a control code assigned via CNT. An interruption to the arithmetic controller is made via the ANT cirucit and the arithmetic controller fetches the received character information, so that data transfer will be made between a terminal and the comupter.
