The gold standard for APRS parsing in pseudo code English is on the www.aprs.org web site:
http://www.aprs.org/txt/APRS-parser.txt
This is the full commented parser from the original APRSdos. It is good up through APRS1.1 and much of APRS1.2. The newest things in APRS1.2 that I need to add are:
1) The new Mic-E Type definitions so that you can recognize Yaesu, and TinyTraks, and other future manufacturers.
2) The new ITEM-IN-MESSAGE format
3) FREQ-IN-MESSAGE format if your code also has RIG tuning control.
4) FREQUNECY parser for tabular display
5) OPERATOR PRESENT BIT ("O" overlay on most symbols)
6) PRIORITY BIT: (uses the case of the E/W byte)
7) SKY COMMAND Parsing and display of community remotes
8) EMERGENCY codes for non Mic-E systems
9) The !DAO! high precision parser
Ill update the parser page above so that it is complete, when I get back from travel.
Bob, Wb4APR
