The K2 serial interface does NOT support DTR or RTS. It only supports three
wires - TxD, RxD and Ground.
One CAN run a K2 with KIO2 or KPA100 on a single serial port and key CW. But
you have to build your own adapter to take the DTR signal and key the rig
through the KEY connector. The adapter consists of a transistor and resistor,
so it can be easily built into a connector housing.
