Terminal control system and method of terminal control

摘要

A terminal control system comprises a control equipment and a plurality of terminals. The processing program held in the control equipment is loaded to each terminal which performs data processing in accordance with the loaded program. Each terminal has a memory for storing modification data for modifying the program to a program having another function. The processing program loaded to a terminal from the control equipment is thus modified to another kind of program by the modification data to provide the terminal with another function. The original function of a terminal is thus capable of being modified or improved by this modification program.
