         It appears I can either use the card for data, or use it for 
GPS, but not both at the same time, even though it uses THREE 
DIFFERENT com ports!  And it only puts out the GGA string, and then 
at about 10-second intervals.  It's kinda strange.

         UI-View32 did finally accept that data, but I was really 
hoping to use the data card for both at the same time, and use just 
the laptop as an APRS setup without any 2-meter rig at all.  I guess 
I'll have to use a separate GPS to get this scheme to work.
