  SIGNALLING TYPE


  This feature selects the signalling scheme to be used in the transmission
  of the Unit ID and Emergency packets.  The Signalling Type may be set to
  one of the following:  MDC600, MDC1200, STAR400E, STAR400P, STAR800E,
  STAR800P, and NONE (where P = Portable and E = Extended).
  This feature determines the range of the UNIT ID as follows:
     For MDC (600 or 1200): 0001 - DEEE (Hex - Except F's).
     For STAR400P or STAR800P: 0001 - 8191 (Decimal).
     For STAR400E or STAR800E, the Unit ID Range is 0001 - 9999 (Decimal).
  The number (400 or 800) for the STAR signalling scheme indicates the
  baud rate.  The Unit ID and Emergency decoders will determine whether
  the Portable or Extended mode is being used.  Selecting NONE, Disables
  this feature.
