Best one around is CommSpy but it's neither shareware nor freeware. I 
also looked a long time before I found CommSpy.

And if you have USB, you can use a Keyspan Twin Serial Adaptor (USB 
to Serial). It has a SPOOL window that allows debugging that's really 
good since you can see (and save) the datastream. Price is probably 
less than CommSpy.

And if you decide to write one, I'd be interested in one (I tried 
CommSpy and presently use a Twin Serial Adaptor for debugging serial 
data streams).
