                            PWR?: power status

12/16/2010    v1.48 	Firmware:
			- Fixed "lockup" problem with input selection.
			- Fixed issue with garbled data occasionally being sent
			  to projectors.
			- Fixed issue with misreporting projector On/Off Status
			  in the DST command.

11/19/2010    v1.42	Firmware:
			- Removed squelching of duplicate commands sent to the 
			  attached projector via the serial port.  Some projectors
			  do not always receive commands correctly or are not
			  ready to accept commands when it was sent by the AVX-400.
			  The previous versions of AVX-400 would not resend the command
			  if state did not change.  This version removes that
			  logic and always resends the command. This applies to 
			  the keypad button event processing as well as input
			  serial port command processing.

09/8/2010     v1.28	Firmware:

			- SP08 keypad not responding correctly with AVX-400.
			  Timing adjustment was required in AVX-400 firmware.

			- Fixed problem where odd and even parity would not
			  function on the serial port interface.

01/14/2010    v1.24	Firmware:

			- ATT? command would sometimes not return a
			  complete string.

			- The range of detection for the input plates
			  was extended to compensate for drifting in the
			  timing signals due to component tolerance and
			  temperatures.  This would sometimes stop input
			  plate from being detected.

			- Mono mode has been added where the left and right
			  audio input channels are mixed together before
			  being output.

			- DST? command now returns an error message if no
			  display is programmed into the unit of it the
			  device has stopped communicating.

			- Added serial pass through mode for the RS232 and
			  axlink ports to allow direct control of the
			  display device and receive feedback from it.

			- The power on reset would not reset all settings,
			  all settings are now reset back to defaults.

			- The power on string is now sent 5 times to help
			  with displays that go into an energy saving mode.
			  These devices sometimes do not wake up first time,

			- Bug fixed when trying to read the flash memory
			  via USB, it would sometimes return incorrect data.

			- Fixed Novara Keypad mute control, it could cause 
			  the unit to lock up and require a power reset.
			
			- To fix a problem discovered with a projector,
			  device interrogation now shuts down for a little
			  while each hour.  The display was previously
			  locking up after several days and would no
			  longer respond to power on commands via serial.

			- Bug fixed where the audio mute control would get
			  confused and forget its current state.

08/26/2009    v1.13	Hardware:
              
			- none
