[ltp] Re: IR-DRIVER-TINY-HOWTO (Linux IrDA on a ThinkPad)]

[Phil Stopford]

Hi folks,

I am a new subscriber to this list and am wading through the huge 
archive of messages that I downloaded for reference from the list 
server. I came across the list via the TINY-HOWTO mentioned in the 
subject (also available from 
http://panopticon.csustan.edu/thood/IR-DRIVER-TINY-HOWTO) and because I 
am still unable to get IrDA running on a Thinkpad 600 using SuSE 9.1 Pro:

/dev/ttyS1 is set up as the IR port according to the information in the 
document (COM2 (io=0x2f8, irq=3)), but uart is not listed in the output 
of setserial. Using the following instructions from the HOWTO :

Add

         alias tty-ldisc-11    irtty

to /etc/conf.modules (this already exists in SuSE 9.1 Pro, but in 
modprobe.conf) and do a `depmod -a'. Now, you need the
`irattach' utility:

         irattach /dev/ttyS1 -s

According to the HOWTO, the detection should start, but this doesn't 
appear to be the case - a CCD shows no activity from the IR port at all.

Assuming that things might have changed, I moved to step 3b, but found 
that irport doesn't seem to exist as a module so 'insmod irport io=0x2f8 
irq=3' doesn't do anything. Has the module name changed since 2000 and 
what should I be using? modprobe irda is possible and in fact SuSE 
allows this to be added to the startup script, but it appears to do 
nothing in terms of IR port activity (checking via CCD).

FIR also seems to be unavailable because there is no module with the 
name nsc_fir in the 2.6.x kernel. The relevant 'insmod nsc_fir 
dongle_id=0x09' instruction doesn't work as a result.

Note that the port does work without issue under XP Pro (verified with 
CCD and Orange SPV cellular phone), but I am keen to be able to put 
linux (of some form or other, not necessarily SuSE) on this machine. I 
can live with the sound dying following a suspend event, but IR is vital 
for on the road email access.

I'd *really* appreciate any pointers, documents or tools to simplify 
getting this working (and any hints about getting the sound to work 
after a suspend event). I'm still wading through the 18,000+ messages in 
the archive, but hoped this post might yield faster results :)

Phil.
