Abstract

PURPOSE:To carry out a switching of circuit in a short time, by securing an automatic switching of the terminal device with an operation given from the terminal device. CONSTITUTION:The operator of a terminal device turns on the signal CI through the terminal device and requests a use of a computer 1. The computer 1 detects not only an on of signal CI but an on of signals ER, DR and RS each. Then the terminal device turns the signal CS on to inform that the terminal device is ready for use. The reception data RD is sent to the computer 1 from the terminal device to be decoded. If the contents of RD is a connection switching request to a computer 2, the switching indication signal on a control signal line 70 is turned on by the computer 1. Thus the switch circuits 60 and 61 are actuated.
