To control the projector using RS-232C commands from a computer, you need to connect the
projector and computer using a commercially available serial cable (cross).
Command Send Format
 All commands use ASCII characters and decimal format integers.
 The projector will return a question mark (?) when it is sent a command it cannot recognize. Any
setting value that cannot be recognized by the projector will be ignored.
 If the projector is performing a process initiated by a previously sent command, a projector key
operation, or a remote controller key operation, send of the next command must wait until the
projector completes the previous process.
