What happens if the computer fails or locks up?
If the ultimate in dependability is desired, the computer can be continuously monitored by a special WatchDog that is designed specifically for that purpose. It is used to check the sanity of the host computer by continuously communicating with it. The Watchdog is connected to the LAN and a separate simple dialer, which calls a programmed number should the computer lockup or otherwise cease to function. Note that the dialer is a separate device, not connected or related to the KenTrol Messaging System.
