Hello !
I have got the problem that I can't establish a connection between Linux
and WinCE via IRDA.
The low level stack of IRDA seems to be OK.
Irdadump says the following:

===========================================================
The problem seems to be on an higher level because it seems that Linux
will only receive packages because ifconfig says the following:
===========================================
irda0 Link encap:IrLAP HWaddr 58:23:cf:c1
UP RUNNING NOARP MTU:2048 Metric:1
RX packets:82 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:8
=========================================
I think there is a problem around the network script of IRDA but I do
not have any knowledge about that stuff.
With a serial cable and replacing ircomm0 by ttyS1 it is working fine.
I am using the SUSE 6.4 distribution with the kernel verision 2.2.14.
The IRDA stuff seems to be the newer one because /dev/ircomm0 is used.
The only thing I found out was that the file /etc/irda/shared was
missing, which seems to be needed from /etc/irda/network.
Please, could anybody help me to solve my problem ?
Richard
By the way: My Linux crashed compleatly (just a HW-rest was possible)
when I changed ircomm. First I had ircomm1 for the device and then I
tried ircomm0 at the file /etc/ppp/peers/cebox. When the first messages
of the HPC are printed at irdump,
the system crashed.
