[aprssig] New OpenTracker+ features

> Also, the Tracker2 has 2 serial ports which allow you to connect both a GPS and computer simultaneously.

Both are buffered for RS232?   Open source!  This is going to fill a
very interesting niche.  When can I get one?  One to start with
anyway...   I've been looking for a basic embedded processor with two
serial ports.  Given the core APRS (and KISS I hope) to start with
that could be just what I need.

Will it still be possible to build a bit regen with the T2 even with
the hardware demodulator?

Thanks,
