K is shorthand for CONV as I recall. To get a later KPC or KAM (from
firmware version 5.0 onward) the command is INT KISS and the RESET. In
other words, one has to *want* to go into KISS mode.

Most likely the outgoing data stream has an embedded Ctl-C that is
bringing the TNC out of CONVerse mode and back into command mode.
Transparent mode is similar to CONVerse except that the TNC is eight
bit clean. To get out of transparent mode, the TNC must receive three
Ctl-C characters. If I recall, Ctl-C could be escaped, but I might be
confusing that with KISS mode which required certain values to be
escaped in the data stream (this is all from memory).
Then there is Host mode...

I'd suggest they try transparent mode, unless the software expects to
be able to put the TNC into command mode with one Ctl-C.
