3.11 Response Frames
A response frame is only transmitted if the corresponding bit (bit 0) has
been set in the FC byte, and if the broadcast address (127) has not
been used as the destination address.
Example: display unit address = 1
master address = 0
Response frame from the display unit to the master:
