3) Control sequence
(1) A command is sent from the computer to the monitor. (Commands should be sent at intervals of at least 600 ms.)
(2) The monitor sends a return command within 600 ms* after receiving the end code. If the monitor fails to receive the
command, it doesn’t send any return command. (*During the power-on/off or input selection process, the transmission of the
return command may take more than 600 ms.)
(3) The computer checks the return command to see whether the command it sent was received or not. The computer must
receive the return command before sending the next command.
(4) The monitor sends various codes other than commands including the return command. While RS-232C control sequence is
in progress, the computer must reject the codes.
Example: Turn the power ON (‘ ’ is for ASCII code)
