I use lirc for my remote control input, but not for controlling my DirecTV
set top box. Right now I'm using my PC's serial port to connect to the low
speed data port on my STB. I use the directv.pl script to control the STB. I
just needed to add the script to my mythbackend setup so the Myth knows how
to change the channel for me. I think I can control a second STB if I add a
PCI serial port card or use a USB to serial converter.
