[aprssig] New OpenTracker+ features

[Scott Miller]

Yeah, they both run through an ST202 transceiver.  If you're not using 
port B, the lines are used for CTS/RTS handshaking.

And it is open source, but I haven't released all of the code yet, and 
haven't decided on the license.  It'll probably be GPL'd, rather than 
BSD like the OpenTracker.  Also, the CodeWarrior compiler requires a 
license for code sizes over 16k.  That means you can compile the OT1+ 
firmware with the free version, but not the Tracker2 firmware.

What I may do is allocate some space for user code, and provide the rest 
as a ROM library that can be linked against.  If I can figure out how to 
do it properly, it should let you compile 16k of your own code without 
having to recompile everything else.

Yeah, you should be able to do a bit regen, though I think that'd be 
easier with a hardware modulator so the MCU isn't so busy generating the 
tones.
