Filed: 1990-09-28
Abstract: PURPOSE:To accurately operate a timer control OS(operating system) similarly to the case with the normal operation even when an event requiring time control takes place frequently by storing a received time request once entirely and outputting only a fastest time request to a time management means. CONSTITUTION:Upon the receipt of a timer request from application programs 1A, 1B requiring time control, a timer monitor application program 2 stores the request into a magnetic disk 4 once in the order of earlier time and gives a timer request closest to a current time to a timer OS 3. Thus, only one timer request is always given to the timer control OS 3, the excess of the processing capability of the timer control OS 3 is not caused and a timerover time with high accuracy is always informed to the timer request from application programs 1A, 1B. Thus, the reliability of a facsimile store and forward exchange is remarkably improved.
