rigctl / hamlib with Kenwood TS-2000

For reliable hamlib connection to the Kenwood TS-2000, make rigctl wait for the TS-2000 to catch up by using the hardware handshake.

rigctl -m 214 -s 57600 -r COM1 -C serial_handshake=Hardware

This solves the intermittent errors with the Kenwood TS-2000 and hamlib like:

read_string(): Timed out 0.2 seconds without reading a character.

Scripts for simple command-line remote control of radios and rotors via hamlib
