Yeah, I tried that. I also used a simpler program that I trust more, 
called Teraterm Pro. Talking to a MFJ TNC with its jumpers set to 
4800baud confirms that the PCs UARTs etc are working at 4800 baud. 
Haven't done a null-modem check but it can't hurt to try to be sure. 
I'll try it all again though and test each step carefully. It could 
just end up being user error, after all! :-)

Uniden were no help. After emailing a careful explanation of the 
problem and the steps I went through to resolve it, I got a one-line 
email saying, "Telephone our support line." Surely email is easier 
than providing phone support? Grr.

Maybe I'll just acquire another GPS that does NMEA 4800 baud without 
hassles. Thanks for your suggestions, everyone.
