Abstract

PURPOSE:To simplify the constitution of an online system and to reduce the cost by converting a stop signal from a terminal equipment into a stop code, and sending and reporting it to a modulator and demodulator automatically. CONSTITUTION:A stop signal, once sent out of a terminal equipment 3, is received by a receiver circuit 16, which outputs (1). At this point of time, a transmission permit signal CS from a modulating and demodulating circuit 1 is (0), so data in the address 0 of a fixed storage circuit 10 is read out to a data register 9 to output a transmission request. The communication controller on a main station side detects the transmission request and when reception is possible, the signal CS is set to (1) and a transmission timing signal ST is sent out. Then, data in the address 1 and addresses succeeding to it of the fixed storage circuit 10 are read out successively to send a corresponding signal sequence of transmitted data SD as a stop code to the modulator and demodulator 1 as a stop code. Thus, the stopping state of the terminal equipment is reported to the main station side.
