* started some work on PTT signaling through serial/parallel ports. 

RIG_PTT_SERIAL is no more, it is replaced by RIG_PTT_SERIAL_RTS and
  RIG_PTT_SERIAL_DTR.
* added comments for rig_get_level and RIG_LEVEL_STRENGTH

* The level value @val can be a float or an integer. See &value_t
* for more information.
*
* %RIG_LEVEL_STRENGTH: @val is an integer, representing the S Meter
* level in dB, according to the ideal S Meter scale. The ideal
* S Meter scale is as follow: S0=-54, S1=-48, S2=-42, S3=-36,
* S4=-30, S5=-24, S6=-18, S7=-12, S8=-6, S9=0, +10=10, +20=20,
* +30=30, +40=40, +50=50 and +60=60. This is the responsability
* of the backend to return values calibrated for this scale.
*
* RETURN VALUE: The rig_get_level() function returns %RIG_OK
* if the operation has been sucessful, or a negative value
* if an error occured (in which case, cause is set appropriately).
