PURPOSE:To supply dummy process data, on/off signal and the like to the receiving and transmitting part of a computer system through a communications controller by fetching process dummy data to a central processing unit through the communications controller in the computer system. CONSTITUTION:The selection instruction of circuits of remote controllers 13A and 13B to which a device to be controlled is connected is inputted through a CRT device. Receiving the selection signal, the control processing part 395 of a process data generator 39 discriminates which said signal comes under, a selection signal, control signal and selection reset signal. When it is a selection signal, such decision is further made whether or not the controllers 13A and 13B are controllable and that the circuit is not used at a control process in sequence. Where both decisions establish, transmitting data, control permitting signal and selection completion signal are sequentially generated. Thus the computer system can be tested by taking a lot of time, and therefore reliability can be improved. Moreover, since a combination test of the remote controller is made unnecessary, the cost of a product can be reduced. |
