Recent discussion and testing has discovered that some manufacturer PJ-Link implementations do NOT respond to lower case commands as required by the protocol. (Some Panasonic and Hitachi models)
The PJ-Link protocol specification specifically states that commands are supposed to be case-insignificant.
This fix may solve the issues with other PJ-Link projectors not responding to this module.
