Kantronics used to be my "favourite" TNC manufacturer, having bout about
a dozen TNCs from them over the years. However, there is the problem with
"delays from KPC3+ TNCs in KISS mode" when run for more than
a week or two, and they don't seem to be willing to do anything about it.

There is the TNC-X that you mentioned with a USB option available, but
setting the transmit level is done with a pot. What about the OT-USB from
Argent Data? Would that satisfy your needs? It has two serial ports as
well as the USB port, and it can do KISS mode.
