Abstract
PURPOSE:To decrease the cost of lines and line installation, by connecting a number of terminal device to data transmission computer with one line interface circuit. CONSTITUTION:An interface circuit generates flags from a flag generating circuit 11 and transmits them to a transmission line 18 via a memory circuit 14. On the other hand, the reception data from a terminal device is input to a register 5 via an input line 1 and at an interface circuit 2. When a flag is detected from the input data a flag detection circuit 7, the data is transferred to an interface circuit 10 and a data buffer memory circuit 14.
