The fact that the serial port and cable work with the MFJ should
indicate that they are both OK, but it never hurts to run a test.

If you have tried all "baud" settings, I would concur with Lynn that it might
be in KISS mode. You shouldn't have any flow control turned on. If you
suspect it is in KISS mode, the trick would be to select the correct baud
rate and send commands from the terminal program to the KPC-2 to get it
out of KISS mode... ALT 192, ALT 255,ALT 192. You press and hold the
ALT key while entering the 3 digits on the numeric keypad ONLY, and
then releasing the ALT key, and then doing it all over again for the next digit.
Alternatively, you could do a HARD reset with jumper K3. The advantage
there would be that you wouldn't have to guess about the "baud" rate and
you could do an "autobaud" routine with the * asterisk, and then do
ABAUD 4800 (or 9600 or whatever) and lock the baud rate to a known
setting. Don't leave it powered on for more than a minute with the jumper
in the reset position. With the case removed, K3 should be on the left
side, two rows of chips from the back of the KPC-2. K3 should be in
the "normal" position when you pop the lid. The "test" position will
do the reset.
After you have established communications...
ABAUD 4800 (or whatever... not slower than 1200)
MYCALL KC8SFQ (ya gotta put something in there!)
TXD 15 (Transmit Delay x 10 ms... the default is 30 or 300 ms but
that is getting kinda long. Experiment to see what your
radio needs, but don't use an excessively long setting.)
PERM (so it will remember all of the settings)
If you want it to be permanently in KISS mode, then do a "KISS ON"
before the PERM. I prefer to have the APRS client drop it out of KISS
mode if the client is ever exited.
If the client is going to put the TNC in KISS mode, the commands are
