The
Serial PC Watchdog is an external device that is used to monitor a
PC in order to ensure maximum system availability. If the hardware
or software locks up then this device can automatically reset the PC.
This device is designed to monitor PCs used in critical applications
such as: File Servers, Voice Mail Systems, ISP systems, industrial applications,
etc. The idea is to make sure the PC is always available and running;
especially for systems that are not continuously monitored. The

of the board. Source code is provided for all included software. The
