Abstract

PURPOSE:To easily cope with program change and to eliminate the need for an external storage device, by storing a control program at terminal device to an auxiliary storage device of a central processing unit and loading it to a terminal device via lines. CONSTITUTION:A control section 9 of a terminal device 8 uses a fixed storage device 10 and forms message when the instruction of a program load is received, and the message is transmitted by using a control section 2 of a CPU 1, exchange network 7 and communication line 6. The CPU1 selects required program from an external auxiliary storage device with a loader program stored in a fixed storage device 3 and loads it to a main storage device 4 and transmits it to the line 6. A control section 9 stores this program to a main storage device 11 and executes the program after the end of communication. Further, the program controlling the CPU1 and the device 8 is stored in the device 5 and at the change of programs, the program is the device 5 is replaced.
