I would like to snoop all the signals on that COM port while the software is working in hopes of finding out exactly how to initialize the hardware and what it spits back when functioning.

This is precisely what I did to fix most of the port initialization bugs in the win32 version of UPLOAD.EXE for my logo editor. The serial port snooper program I used for that is now one of my "must have" utilities.

The utility you want is portmon.

Ah, good old sysinternals.
