Define the alias for a transciever that is connected to an IO module for automated control.

Define the alias for a transciever that is connected to an IO module for automated control.

The current alias formats are:
  AR26-alias.chan 	Altanta Micro 1-26 GHz  reciever
  AR18-alias.chan 	Altanta Micro 1-18 GHz  reciever
  AT18-alias.chan 	Altanta Micro 1-18 GHz  tramsmitter
  AX18-alias.chan	Altanta Micro 1-18 GHz  reciever/transmitter pair

Where alias is the ipmice device alias and chan is an optional channel number 1 or 2.
If the channel number is not specified, it follow the card IO module number.

The devices will then be controlled by the ICE libraries via the xcvrlib.c code.
The RFFREQ and RFATTN flags or setKeys will be intercepted and handled appropriatley.
This works with the IO modules to properly handle the inverted ranges of the AR/AT 
devices, bypass modes for low freqs, and setting the IO module to an offset IF to
handle center frequencies other than the allowable discrete AR/AT values.

The MUXCLK=PX or PREF flags are used to set the external clock settings.
To override this, use the XREF=x flag where x = 0:Internal 1:Front 2:Back.
This is the preferred interface to the ICE AR/AT setups.
