Couldn’t you just use dire wolf? It is a free soft Tnc
that supports 9600

Direwolf is awesome..
I’m a huge fan of direwolf. Pair a usb soundcard with
a cheap radio and you
can easily have a ~$100 dollar aprs rigs that can tx and rx.
We still, even after all these years, have a real lack of a 'good'
higher speed packet radio. The cheap (BaoFeng?) radios will work
(sorta) for APRS but at slower speeds (maybe up to 3600?) and they
have a TXD an order of a magnitude longer than acceptable.
There are some options for 9600 (or faster) but there are still issues
and challenges.

I had to spend more than $100 total to do 9600 I'd
question the whole
The problem with Packet Radio is still the 'radio.' A reasonable 9k6
station is about $250 - but at that price better off just getting an
off the shelf Kenwood TH-D710 which works well at 9k6 and offers a
second channel.
Adjusted for time - these are still way cheaper than the $500 I paid
in 1986 for my first 1200 baud packet station consisting of a
Kantronics KPC and Yeasu HT.
The article on 9600 packet in last years DCC proceedings (PDF is
available on the web) is a good review of the technology and is a
start for looking at radios.
