Has anyone out there created a RS232 control macrol for the Key Digital Auto switching component switch? Is it even neccassary. I plan to use this for my HDTV set top box and my HTPC. I don't want to have to power down my HTPC just to watch the set top box and I don't want to have to get up fiddle with a switch in front of guest for my all automated Home theater. Any since the pc will always be on I need to be able to remote switch when I watch the HDTV stb.
