DoorMan is a small TSR program. Graciously contributed to this package
by Chris Smith. It contains the 'watchdog' function and it should be
loaded in the autoexec.bat file. The 'watchdog' function is used during
a remote shell from the host mode operation.
Chris has a companion program called ChekTime available. The purpose
of ChekTime is to enable DoorMan to monitor time limits during execution
of door programs.
