         I think I had asked about such a thing and came up 
short.  What I ended up doing was using UI-View for APRS and 
configuring it to output GPS data on a different com port.  In 
addition, I had to use a "bridge" to make the com port available to 
my Street Atlas program.

         Today, were I trying to use a GPS with some APRS program, 
and keep the computer time correct, I would use a program to get the 
time from the internet, if that is possible.  In the end, it's a lot simpler.
