Take UI-View right out of the equation. Get your TNC going with a terminal
program first so you can determine the settings. If you can't talk to it
with a terminal program, it won't get any better or any easier in UI-View.
It would be a tedious procedure to go through and try every baud rate that
the terminal program was capable of in combination of 7 or 8 data bits,
odd or even parity, and varying stop bits. Do you have the documentation
for the TNC? If not, is there anyone on-list that can tell you how to do a
full reset to the TNC-200 and what the default settings are? Without
knowing what the current settings are, or what the default settings are
after a reset, you might have to resort trying many combinations until you
come up with the right settings.

If it's "stuck" in KISS mode, try alt-192, alt-255, alt-192. Try also alt
0192, alt 0255, alt 0192. I hadn't heard of "Q" before. Maybe it's a
"Paccom" thing? For a Kantronics TNC, the sequence would be to hold down 
the ALT key, type in 192 (or 0192) and release the ALT key, and then 
repeat it for 255 (or 0255) and then again for 192 (or 0192).

The following page may or may not be useful - after you get the serial
port settings correct. Strangely, I couldn't see a parameter there for
setting the "baud" rate on the serial port. Of course, you would have to
be set at the right settings to adjust it.
