You may want to read the comments in the startup script files located in
/usr/local/share/xastir/config
The more generic tnc-startup.sys might be a better fit.

Interface Control, do you see an error message in the terminal?  First
thought is your username might not be a member of the dialout group and
doesn't have permission to open the port.  I do note you were able to
access it with minicom, though.

Another option would be to manually put the TNC in Kiss mode and create a
serial Kiss TNC interface in Xastir.  With that setup I don't think you
would need a startup or shutdown file referenced in the interface
configuration.  If desired I believe you could also create your own startup
files that would put the TNC in Kiss mode to start and take it out when
exiting.
