Abstract

PURPOSE:To cope with the extension easily without adding a central processing unit and a storage circuit attached thereto by writing a program to be added to an idle area of the storage circuit from an auxiliary storage device in extending a terminal line so as to start the additional program in addition to the start of the existing program. CONSTITUTION:In extending the terminal line, that is, a terminal 103 and a terminal accommodation circuit 113, a maintenance terminal 141 is controlled to read a program to be added from the auxiliary storage device 151 and the program is allocated to idle areas 221, 222. The program is added to the areas 221, 222 corresponding to the addition of a processor in a conventional system. After the terminal line is extended, the monitor program of the area 231 starts existing program areas 211-213 to start the added program areas 221, 222. Thus, the terminal line is extended easily.
