George,
Do not plug the USB to serial adapter directly into the K2 AUX I/O
connector, plug the adapter into the special cable made to connect to a
computer serial port.
The AUX I/O connector contains some non-RS232 signals that are used to
control external Elecraft devices (KAT100, KRC2, XV series transverters)
and those signal lines will not withstand RS-232 levels - in other
words, you can damage the K2.
USB to serial adapters differ, even those with the FTDI chip. Some do
not like to run at the slow 4800 baud rate of the K2. If one does not
work well, try another brand.

My K2 has KIO2 RS232. Most of the computers now does not have the RS232 DB9
port. I wonder if I could use a FTDI serial to USB
cable to connect my K2.
