  What you sent me is exactly what I'm looking for.  However, I couldn't download "validation.c"
   
  The following link appears to be dead.
  
http://www.cnunix.com/ftp/hamradio/tapr/aprssig/aprsspec/aprstcp/ 

  Please help me get a copy of validation.c
   
  Thanks for your help

Google is your friend.

The first part is the hard part, the rest is just connecting to the 
APRS Internet System, here is info on the login string

http://www.aprs.net/valid.html

If you don't have the validation number for your call, here is the code

validation.c

Then just form an APRS packet and send it. The APRS protocol 
specification is at
