KISS

One final sequence of value (particularly for PC compatible users) is the "Leave KISS Mode" se-
quence:
C0 FF C0
If for some reason, you have INTFACE KISS and PERMed, when you turn the unit off and then on
again, you will be in KISS Mode. The only way to leave this, would be to perform a hard reset or
use the TCP/IP command to leave KISS Mode, or to send the C0 FF C0 sequence from your key-
board. The PC compatibles offer this last opportunity by following this sequence:
Press and HOLD the ALT key. Type the numbers 192 from the numeric KEYPAD – Not the key-
board. Release the ALT key.
Press and HOLD the ALT key. Type the numbers 255 from the numeric KEYPAD – Not the key-
board. Release the ALT key.
Press and HOLD the ALT key. Type the numbers 192 from the numeric KEYPAD – Not the key-
board. Release the ALT key.
Now, if the terminal program you are using, sent all those characters, you will be out of the KISS-
Mode. Remember to PERM the INTFACE command to something besides KISS if you do not want
your TNC to be in KISS Mode when you turn the unit off and then back on.
Although not currently implemented in the TCP/IP software, the KAM and KPC-4 are capable of
supporting dual-port KISS Mode operation. This is accomplished by using the high nibble (4 bits)
of the command byte to indicate, which port to use. A non-zero high nibble, with the low nibble
being the previously defined TYPE, will address the KAM HF port or the KPC-4 radio Port 2, while a
zero high nibble will address the KAM VHF port or the KPC-4 radio Port 1.
