c validating filename - Config file etcconf dudev needs updating
I am not saying that my way is the best way by any means.
You should probably read the other articles below first to better understand things.
First thing - I alway buy my hardware that I know is linux supported and has good drivers.
There is also support for multiple Ir LAP connections, via several Ir DA(TM) devices at once.
The Linux/Ir DA project started at the end of 1997 and its status is still experimental, so please don't expect every feature working straight.
So get to know your hardware, I can't say that enough as it will save you a lot of headaches.
