I've never touched a Dstar rig, but my understanding is that while you
talk in low speed data mode, 1/2 of 9600 is used for voice, the other
1/2 is used for 4800 baud serial data... so in an ideal world, I could
hook my GPS up to the serial port and while I'm talking 100% of my GPS
sentences are passed thru to all receivers as if the TNC were in
converse mode.

I"m gunna ask the dumb question....

How do you know WHO is sending the data?  If it's converse mode, only
the data portion of the packet shows up, none of the headers show up.

Sounds like we need to take GPS data and encapsulate it in a 3rd party
formatted frame.... sounds kinda clunky.

Am I on the right track?
