Spaces and tabs can be used to improve readability and will be
ignored by the projector. All commands must end with a carriage
return (ASCII hex 0D), shown as [CR] below, to signify that the
projector can now read and execute the command.

Operation commands tell the projector exactly what to do.
Commands start witha letters:
op for operations commands.
