Abstract

PURPOSE:To achieve start control saving the hardware, by minimizing the effect on other line control adaptor. CONSTITUTION:A line common control section 1 consists of a control circuit 2, a start flag 3 storing the indication of start, an address register storing the line address indicated of starting, a scanning counter 5, a switching circuit 6 and a data buffer 7, and it is connected to a data bus 8 and a control bus 9. A line control adaptor 10 consists of an adaptor control circuit 11, a start-enable-flag 12 which displays the start reception enable being logic ''1'' when the preparation of reception of start information is finished, processing request flag 13 displaying the processing request, data buffer 14 in an adaptor, common bus 15 in the adaptor and a plurality of line interface circuits 16.
