It wouldn't - but control of the lamp power must be through a different port 
than control of the video output to the screen. You can stop the screen 
refresh simply by telling the video scans to turn off. My query was whether 
there are two calls (set lamp lavel, control video card) or just one (which 
would do both).

<grin> it's not important...
