Thanks for the code segment. I may have asked the wrong question.

Here's another try: can this box do everything a good TNC can do, and
what modifications need to be made to programs that expect a standard
TNC?

I think you're severely confused about what the rigblaster is...
it's a serial interface, used primarily to assert PTT and do
some audio level management for digital modes. It has
absolutely nothing even REMOTELY close to having TNC
functionality.
