[Xastir] GPS waypoint question

You're missing the point a little.

The OpenTracker (my OT III anyway) outputs the string TO TH GPS. Even my 
old Garmin 12 will translate this to a way point. Unfortunately the 1 
1/2 by 2 inch mono screen doesn't give much. No Maps etc. It WOULD be 
nice to output the string from the OT3 directly to Xastir and have  full 
UMPC based mobile tracking without a full fledges TNC....

At least I think thatd what the OP is after
