PURPOSE:To obtain a device which exclusively occupies the communication circuit corresponding to each group, by setting the computer group in accordance with the contents of process and the terminal device group in accordance with the input/output information respectively. CONSTITUTION:For a device that connects plural computers or terminal devices to a communication circuit via the communication controllers, the routes 10, 20 and 30 are processed by computers 1-3, 3-5 and 4-6 respectively, for instance. The process request is delivered from the computers 1-6 respectively to secure the process states RU1(10-30)-RU6(10-30), the reservation states RE1(10-30)- RE6(10-30) and the waiting states WA1(10-30)-WA6(10-30) via communication controllers 1'-6' and in accordance with routes 10-30 by which the state of each computer is procesed. After this, the state is controlled by the controllers 1'-6' for the computes 1-6 plus circuits 12, 23-56. Thus the communication line is controlled in accordance with each state. |
