Mic-E is just one format of APRS, which is normally used over 1200 baud
AX.25. You'll want to look up the APRS specification.
There are plenty of open source APRS clients out there. My OpenTracker
series will decode Mic-E, but won't encode it because I feel that Base91
is a better solution. The devices will still work as mic encoders,
sending a burst when you unkey, just not in the format normally referred
to as Mic-E.
