Abstract

PURPOSE: To eliminate the need for a program of pin array by making it possible to distinguish between a control code transmission mode and control code transmission mode automatically by a data communication unit mode and data terminal equipment mode.
CONSTITUTION: According to whether a controlled equipment is a data terminal equipment or data communication unit, an input output unit operates as data communication unit DCE mode or data terminal equipment DTE mode. In DCE mode, if transmission would not be done twice continuously even with ready- for-receiving RR and data-equipment ready modes both OFF or either one ON, or when transmission PS is OFF even after it is ON further twice or once, the control code transmission mode is put in effect. After transmission request RS is ON twice continuously, the operation is effective in transmitting code transmission mode as far as no interruption. In DTE mode, the control code mode allows the operation similarly except when ready for sending CS or receiving carrier detection CD is ON twice continuously.
