Abstract

PURPOSE: To inform failure with a simple constitution, by operating the monitor timer when information exchange is made between the terminal unit and the host computer, and producing the alarm if no response is fed from the computer for a given time.
CONSTITUTION: The character display terminal unit 1 is connected to the host computer 4 via the communication line 5, and the information input via the terminal control section 6 is fed to the computer 4 by operating the keyboard section 3 of the terminal unit 1. In this case, the information is transmitted to the line 5 and the transmission signal 7 is fed to the monitor timer 9, the timer 9 is cleared to zero and the clock start is made. Further, if the ON-line system is normal, the result is fed to the control section 6 through the line 5 from the computer 4 after a given time and the result is fed to the display section 2 and displayed. Further, if system failure causes that the result from the computer 4 can not be received within a given time, the reception signal 8 is fed to the timer 9 from the control section 6 and the alarm display set 10 is operated with the time-out signal 11.
