[Xastir] Xastir on raspberrypi to SCS PTCIIpro for Robust packet Radio

[Menga]

Curt,
in order to connect Xastir to the SCS PTC modem, I used the interface 
"Serial KISS TNC". The configuration window of this interface doesn't allow 
to define Setup and Shutdown files.
I'm surprise that the modem worked correctly, even if not KISS message 
appeared in the information window of the modem, maybe it was a coincidence. 
In fact I'm used to send in advance to the modem baud rate of the 
trasmission (300 bps), the timing etc.
To be able to specify setup and Shutdown files I have to use the interface 
"Serial TNC". The two configuration windows, a part from the fields for the 
file names, are almost identical. I will try.
Then I have a question: which difference exists in the behaviour of Xatris 
in selecting one or the other of the two configurations?

I don't believe any of the Xastir developers have one of these modems. At 
least I've not heard of any that do.

It's pretty easy though: Take one of the standard scripts for "startup" and 
one for "stop" in /usr/local/share/xastir/config/, copy them to new 
filenames (maybe your "callsign.scs"?), then modify them to hold your TNC's 
commands. You can test each command from a dumb terminal first, connected to 
your TNC, while you work on the scripts.

Once you have them the way you like, change Xastir to use those filenames 
instead and you're good to go. Save those files away in a good location in 
case your hard drive breaks, so you don't have to go through the process 
again.

If you get something you like, consider donating them back to the project 
and we can add them to Xastir.
