Hi,

somehow I can't get IrDA to work on my Fujitsu B110 laptop. I am 
using SuSE Linux 7.0 with either Kernel version 2.2.16 or 2.4.2 and 
have installed the latest irda-utils, but I even fail in using SIR.
Can anyone please give me a hint what I'm doing wrong?

Björn Rhoads says in his mail 
(http://www.pasta.cs.uit.no/pipermail/irda/2000-May/000064.html), 
that the B110 uses a SMC FDC37N769 chip which is not recognised by 
smc-ircc or findchip. His hardware resources (io, irq) are exactly 
the same as on my computer (SIR io=0x2e8, irq=3 => /dev/ttyS3, FIR 
io=0x118, dma=3).
I think at least SIR should work, because the ir-chip behaves like 
any serial port... so no special driver should be necessary.

When I'm trying the tips from the "IR-DRIVER-TINY-HOWTO" 
(http://www.pasta.cs.UiT.No/pipermail/linux-irda/2000-
April/001360.html), I get the following results:

(with FIR disabled in the BIOS)
# irattach /dev/ttyS3 -s
Obviously works fine, loads the "irtty" and "irda" modules, the 
network device "irda0" can be seen with ifconfig, but does not find 
any irda-devices (I am using the Siemens S25 phone) (in 
/proc/net/irda/discovery), and also minicom cannot communicate with 
the S25-modem (/dev/modem = /dev/ircomm0). Normally, under Windows, I 
can also see the Ir LED flashing, which is also not the case under 
Linux.

(with FIR enabled in the BIOS)
# setserial /dev/ttyS3 uart none
# modprobe irda
# insmod irport io=0x2e8 irq=3
Using /lib/modules/2.4.2/kernel/drivers/net/irda/irport.o
# ifconfig irda0 up
SIOCSIFFLAGS: Resource temporarily unavailable
# irattach irda0 -s

=> Only "irport" and "irda" modules are loaded.

Or if I try:
# modprobe smc-ircc
/lib/modules/2.4.2/kernel/drivers/net/irda/smc-ircc.o: No such device
Hint: insmod errors can be caused by incorrect module parameters, 
including invalid IO or IRQ parameters
/lib/modules/2.4.2/kernel/drivers/net/irda/smc-ircc.o: insmod 
/lib/modules/2.4.2/kernel/drivers/net/irda/smc-ircc.o failed
/lib/modules/2.4.2/kernel/drivers/net/irda/smc-ircc.o: insmod smc-
ircc failed

My /etc/irda/drivers looks like (as decribed in the mail of Björn 
Rhoads):
[...]
case "${action:?}" in
'start')
        setserial /dev/ttyS3 uart none
        modprobe smc-ircc
        /usr/sbin/irattach irda0 -s
        echo 100 > /proc/sys/net/irda/slot_timeout
    ;;
[...]

Thanks,
Christoph
