was enough to get everything working. After that the 8210 appeared in
the irdadump logs, which it didn't previously.
(What do I need in order to make irdadump output anything? load which
modules etc?. I haven't got any output so far.)
I've successfully established a PPP connection over the irda link,
with an average ping of about 6 seconds %-)
(Are non-GPRS connections (forgot the name, those connection oriented
ones) better?)
But you shouldn't use /dev/ttyS1. You should load the ircomm module
and use /dev/ircomm0.
How to use ircomm? Can I use minicom on it?

What kernel bug ?
The one that crashes the machine. (fiddling with ttyS1 shouldn't do
that, right?) Ok maybe if I do everything as I should and hold my
breath, it won't happen anymore.

my purpose?
The irda port on the mac can be used as a SIR device (what you're
currently doing), I think it could be used as a FIR device too but
there is currently no driver for that (assuming it's possible at all,
which I'm not sure).
I haven't used this irda setup for a while, but I have some time this
week to play with it if you need some more help. Google is your
friend, you can also find some help on mobilix.org^Wtuxmobil.org
(although the docs often cover FIR devices, there are some bits of
information on SIR devices).
I haven't really found much information. The best so far is:

Is it correct that ircomm is a layer above one of SIR|FIR|..?
So should I first get SIR working? Using minicom for debugging?
cat /proc/net/irda/discovery never showed anything apart from these lines:
"IrLMP: Discovery log:
"
More questions:
- where does the infrared beam leave the mobile? From what I read in
the nokia docs, it's a laser diode, not an led. So maybe it's not
hidden behind a black (IR-permeable) plastic window, but instead,
probably, in a slit on the right side, about where usually your thumb
is when holding the mobile to the ear.
- is there maybe any real lowlevel access to the infrared port, so I
can see if light is physically entering the laptop ir port even if
drivers are not working?
Thanks
Christian.
