* Implements IHardwareController using the modem-control lines of an RS-232

|
* (or USB-serial) port. RTS and/or DTR are used as PTT outputs; CD, CTS,
|
|
* and DSR are used as COR/squelch inputs. The config parameter selects which

* config documentation).

* This controller does not transfer any data — it only toggles the control
