I have two IR transmitters, each on a serial port of my backend.   My cable 
provider won't enable the serial ports on my stb's.  

I had to hack together a custom lirc module to let lirc deal with two separate 
serial port IR transmitters.  I copied the entire lirc_serial module in to 
lirc_serial1, and edited the new module appropriately.

I have two separate change channel scripts, which I call tunetv1 and tunetv2.  
The only difference between the scripts is the device in the irsend commands.

Since my STB's and transmitters are very close to each other, I have to be 
very careful not to get the signals mixed up.  I built little tents out of 
egg cartons to hide the STB's IR receivers from each other.

Hope this helps,

Mark
