Yes I am, and it do work ok if you want to send to the first device you
find, but I'd like to choose one specific if there are more than one
discovered.

Ok, I get it. I had some trouble with getting obex to try to send to the
correct address at first since the Palm V changes addresses each time it
sees a new discovery sequence (why?) and the cache contained the older one
at some points when I was turning on/off the discovery manually. When I
tried to set the discovery timeout to 1 sec the Palm V went crazy and
reported different addresses in almost every response.
And another question (that I've asked before), when I've sent something
from the linuxbox, irlap resends a number of receive ready (?) frames
which renders the irlink unusable for about ten seconds (or 24*500msec).
I dont know if it wants the other device to reply but the Palm V stays
silent. Is it possible to avoid this? A few irdadump lines :

11:45:33.391866 rr:cmd > ca=d2 pf=1 nr=7
...
thanks alot for the help. and great work on these irda drivers btw.
