3.3 Remote Control Pass-through mode
When PC sets the LCD display to Remote Control Pass through mode, the LCD display shall send a 7 bytes
packet (followed by "CR") in response to RCU button activation. Note, that in this mode the RCU shall
have no effect on the LCD display function. For example: "Volume+" will not change the volume in the
LCD but only sends "Volume+" code to PC over the RS232 port.
