  67* The capabilities ioctls can inform you of the capabilities of each phone
  68* device installed in your system.  The PHONECTL_CAPABILITIES ioctl
  69* returns an integer value indicating the number of capabilities the   
  70* device has.  The PHONECTL_CAPABILITIES_LIST will fill an array of 
  71* capability structs with all of its capabilities.  The
  72* PHONECTL_CAPABILITIES_CHECK takes a single capability struct and returns
  73* a TRUE if the device has that capability, otherwise it returns false.
