Are you familiar with this APRStt implementation?
APRStt Implementation Notes [ download ]
Very few hams have portable equipment for APRS but nearly everyone
has a handheld radio that can send DTMF tones. APRStt allows a user,
equipped with only DTMF (commonly known as Touch Tone) generation
capability, to enter information into the global APRS data network.
This document explains how the APRStt concept was implemented in the
Dire Wolf application.

This example illustrates how APRStt can be integrated with other applications such as SARTrack, APRSISCE/32, YAAC, or Xastir.
