I can confirm, that this now works. I have created a template called "LCD Flat Panels" that were created as a device under TV's/Projectors/LCD's drop down. I chose rs232 as the control group, created a new group called "LCDs" and added the on off commands using:
system("xset dpms force off")
system("xset dpms force on")
Now it shows up as a TV device in the AV wizard, and Sara sees it as a TV. Now when I call the display off button from the orbiter, or press power on the remote to call it, it blanks out the screen. When you hit the menu button on any of the remotes, it comes back, and also after it sits idle for too long, 5 minutes I think, it blanks the screen as well.
Works just like it is supposed to. But I am looking forward to Thom's template in the upcoming release.
Thanks and Regards,
