There's also the Perl APRS code that Ian wrote (the APRS spec
editor) which validates packets.  I should have a copy of it around
somewhere if you can't find it on the 'net.  That would be excellent
code to have around as an example, just because it was at one time
the most complete Perl decoder implementation.

On SourceForge I believe there are C++ classes and perhaps Java code
for parsing APRS sentences, and of course the Xastir project
(SourceForge again) has a bunch of C code.  It's a _bunch_ of C code
though!

I also have Perl code for authenticating on the 'net if you'd like
that.  It's a direct Perl translation of the C-code that Steve Dimse
published and I use it extensively in my Perl scripts which inject
objects into Firenet.
