I found the problem.  When I installed C7 somewhere in the docs it
said something about redirecting kernel debug messages.  I don't have
a second monitor or a dedicated terminal on com1, so I redirected the
debug output to nul.  In system.ini I added:
[debug]
OutputTo=nul

This was the problem!

I'm not sure what to use so I just put a file name in there for
right now.  Fixed the problem.
