[mythtv-users] Detect IRD on/off status via serial port w/photocell

I would like my channel change script to detect the state of my IRD (dish network cheapy).  I see the IRD has a bright yellow POWER ON led on the front.

Has anyone tried connecting a photocell to a line on a serial port (eg: CTS) and see if the POWER ON light can be detected that way?  Seems simple....but just slightly above my skill level.
