PURPOSE:To simplify the constitution of a low-order information processor subjected to remote control by providing a circuit, which decides only a stop frame, in a line transmitting and receiving part in the low-order information processor. CONSTITUTION:Data including line control information which is transmitted from a high-order information processor 1 to a low-order information processor 2 subjected to remote control is received by a line transmitting and receiving part 3, and it is detected whether this data is the stop frame or not by a stop frame detecting part 9. If it is not the stop frame, data including line control information is written in or read from a memory part 8 through a line corresponding part 4 by the control of a direct memory control part 6 or a microprocessor 7. If the stop frame is detected by the stop frame detecting part 9, the microprocessor 7 is stopped or reset, and an initial program is loaded to the memory part 8. |
