ESC/VP21 Commands

Command List

When the power ON command is transmitted to the projector, the power
turns on and it enters warm-up mode. When the projector's power has
turned on, a colon ":" (3Ah) is returned.
When a command is input, the projector executes the command and
returns a ":", and then accepts the next command.
If the command being processed terminates abnormally, an error message
is output and a ":" is returned.
