Abstract
PURPOSE: To make suitable the management of the terminal device, by providing the flag information permitting or inhibiting the reception/transmission of data to the memory constituting the system and controlling this with the input device.
CONSTITUTION: To the central processing unit CPU, the main memory MM, a plurality of terminal devices TS and input and output device I/O are connected via the bus BS to constitute the computer system. In this constitution, the main memory MM is provided with the program CCP managing the logical connection and disconnection of the terminal device TS, the desired TS is connected to the bus for a given time with the instruction from the input and output device I/O to operate the computer. The connection and disconnection flags in the program CCP have the logical numbers No.1WNo.3 given to each terminal device and the column storing the control references CT11WCT13 for the number of sets of the terminal devices, and the device I/O designates it, and only the terminal device designated is connected to the bus BS.
