You are far to late Bob, German based "The Firmware" has been around for 
at least a decade maybe longer and is far different from tapr and aea 
format, that is why dosaprs doesn´t work on european tncs without an 
eprom swap.
That is also why programmers keep telling you and others not to depend 
on the convers mode of a tnc as a software interface.
There is a common interface for all tncs already and it is called KISS, 
suport that and you will not have to code for future tncs.

If you don´t know how to interface KISS then check the open licenced 
software like xastir, digi_ned etc. for portable code.
