PURPOSE:To detect the stop of sending of check data which the abnormality is generated to know easily the generation of abnormality by incorporating normally software for sending check data from a computer main body to a monitor at every specified time interval. CONSTITUTION:The titled system is constituted of the computer 1, the monitor 2 for deciding the abnormality of the computer 1 and a communication means 3 for transferring data between the computer 1 and the monitor 2. The computer 1 sends check data consisting of HI data and LO data to the monitor 2 during a check data communication period (t) at every prescribed time interval T. The continuous periods of said HI and LO data are compared with a prescribed set time respectively, and if the continuous period exceeds the set time, the abnormality is displayed. Thus, the abnormality of the computer body can be easily outputted. |
