I should clarify: these are for monitoring a local program on a *BSD
box (similar to using strace on Linux/SysV).

Doing some sort of man-in-the-middle monitoring is a hassle due to
baud rates and everything.

Also, if you want to watch the Windows program interact with the UPS,
take a look at portmon from the Sysinternals collection (not sure
where it went now that the author works for Microsoft or whatever).
