Abstract

PURPOSE:To prevent malfunction due to line noise and to perform sure folding control, by controlling data transmitted to a MODEM through superimposing instruction information and starting the operation just after the reception of specified bit train. CONSTITUTION:When a folding is set to a remote location, and when a folding set instruction switch 101 is depressed, a determines set instruction bit train is transmitted to a line 11, the bit train folded at a remote location is detected and a remote folding display 24 is illuminated. If there is any error, even one bit, since a counter 22 is restarted, folding in error can be avoided. If a remote location folding is released, when a folded release instruction switch 102 is depressed and release instruction bit train is transmitted to the line 11, the folding is released at a remote location and normal data not the instruction pattern is transmitted, the display 24 is distinguished.
