PURPOSE:To connect an optional number of terminal equipments to respective computer systems by providing a non-instantaneous switch to change over a computer system and respective terminal equipments respectively and a means to give a switch change-over signal with a terminal control device which controls to connect a terminal equipment to a computer system. CONSTITUTION:A processor 11 of a terminal control device 8 reads the program stored in a ROM13 and is operated. The processor 11 detects the condition of an operating part 17 through an operating control part 16, reads after the condition is stored in a RAM12, controls a switch control part 19 in accordance with the condition of the operating part 17 and changes over switches 21 and 22. The processor 11 completes to connect, change over and control the switches 21 and 22, based upon the switch control information of the RAM12, the processor displays the condition of the switches 21 and 22 through a display control part 15 to a display part 14. A display part 9 of a computer system 1 and a display part 10 of a computer system 2 through an interface part 18 display the condition of the switches 21 and 22. |
