Abstract

PURPOSE:To remarkably decrease the capacity of hardware display line and to make unnecessary a number of signal lines, by displaying the status of data reception and data communication as the signal fed from the opposing party and fed to the party. CONSTITUTION:In receiving the data RD signal fed from the opposing party among the signals from the MODEM interface 1, the firmware is started with the signal requesting the character service received from the hardware, and the reception character service is made and the signal is given to the pulse generating circuit 25, and the output is stored for a given time and is input signal to the lamp driver circuit 25. In sending the data SD signal to the opposing party, the firmware is started with the signal requesting the transmission character service from the hardware to perform the transmission character service, and the signal is given to the pulse generating circuit 26, and the output is stored for a given time and given to the lamp driver circuit 210. Thus, the state of data reception and transmission is displayed on the lamp 211 as RD and SD signals.
