 ******************************************************************************
 *  DESCRIPTION:
 *  This function is called when the phone receives a modem command while
 *  in the Display 12 State.  The behavior of the Display 12 State actually
 *  does depend on the nature of the command received.  The commands are
 *  generally split into three categories: those that only propogate, those
 *  that always propogate and exit, and those that propogate and may exit
 *  depending on the current exit state.
