10.3.3. Remote Control Pass-through mode

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