Abstract
PURPOSE: To reduce the cost by making unnecessary the MODEM between the terminal and the adaptor, by providing the signal generation means of carrier detection and transmission enable at the line adaptor between the communication control unit and the terminal, and folding means to the signal from the terminal.
CONSTITUTION: The direct connection line adaptor 4 is provided between the communication control unit main body 6 and the terminal 2. The unit ready signal ER from the terminal 2 is folded as the data set ready signal DR, and the transmission request signal RS from the terminal 2 is folded as the transmission enable signal CS. The signals ER and RS from the terminal 2 are inputted to the gate 6 and outputted as the carrier detection signal CD. The unit ready signal ER and the transmission request signal RS in the adaptor 4 are inputted to the gate 7 to form the carrier detection signal CD to the terminal and the transmission enable signal in the adaptor CS. Thus, the part between the terminal 2 and the adaptor 4 is the same interface as via the MODEM, and the terminal can perform the same operation as the connection of MODEM.
