Hi,

the first step is to find out which infrared chip your computer has built in. To find out, enter
Code:
findchip
You can use the results to search on goole, in this forum or ask more specifically again.

For my VAIO, I have:
NSC,PC87338,11.2,0x398,0x3e8,0x3e8,10,0,1,0,1
and I can get it to work with:

Code:
# for Sony VAIO
 setserial /dev/ttyS2 irq 10 port 0x3e8
 
 # this is fot FIR to work, don't use this for SIR
 setserial /dev/ttyS2 uart none
 
 # to use the FIR driver
 modprobe nsc-ircc dongle_id=0x09 

 # brings up irda0 network device
 irattach irda0 -s 

 # The following devices are in range:
 cat /proc/net/irda/discovery
Greetings,
probono
