Just need some Widget(s) to do a SERIAL port command to my Lyngdorf MP60 prepossesser and return the status on which INPUT is selected (like Roku box), which PROCESSING option is selected (like ATMOS), and which VOICE PROCESS option is selected (like NEUTRAL). Just display on the remotes screen which one of these is currently being used. That's it. There are SERIAL RS232 commands for the Lyngdorpf to do all those inquires.

Ive tried to do it. The widgets programming is not making much sense to me.

There is a widget posted here, remotecentral, that does this type of SERIAL inquiry only its for a Marantz receiver/processor. I tried to mimic it but no glory.
