***Monitor return source code ***
Didprintf("(%d)",GetSETID()); // Set Id
Didprintf("BRT=%d\r\n",GetPictureBrightnessValue()); // Brightness Value
putchar(ACK); or putchar(NACK); // Ack or Nack.
Ack : Command excute ok.
Nack : Head and ID are correct but others command is not correct format.
If Head or ID commands are incorrect(format or range) monitor don’t reply.
Because monitor consider other type control command(ex auto calibration) if Head is not correct(format
or range).
And Monitor consider other monitor control command if ID is not correct(format or range).
Ex1) Set id = 10 , Brightness change 8 to 9.
