Hi there,
I've spent the past three night trying to install
irda on my laptop in order to have it sharing data with either
a Palm IIIxe or an Ericsson R320s. Despite the fact that I'm _not_ a
linux newbie, I really was not able to manage the task.
Any help is more than welcome. Here I describe the situation at my best
I've a NEC Versa 6200MX, with RedHat 6.2 installed.
In the BIOS I set the Irda to SIR mode. Anyhow
'findchip' (from irda-utils)
finds one of the supported chipset for FIR: i.e:
Found NSC PC87338 Controller at 0x398, DevID=0x0b, Rev. 1
SIR Base 0x3e8, FIR Base 0x3e8
IRQ = 9, DMA = 0
Enabled: yes, Suspended: no
UART compatible: yes
Half duplex delay = 0 us
I'm running kernel 2.2.17-14 the last update by RedHat.
At boot I can see two serial port. The normal one ttyS00, and ttyS2 that
I assumed it was the SIR, also from the fact that has the same mem
address as reported by 'findchip'. Relevant 'dmesg' output follows
...
Serial driver version 4.27 with MANY_PORTS MULTIPORT SHARE_IRQ enabled
ttyS00 at 0x03f8 (irq = 4) is a 16550A
ttyS02 at 0x03e8 (irq = 4) is a 16550A
...
I patched the kernel with the last patch-2.2.18-23-irda1 from irda web-site.
It applied flawlessly except for an apparently not important (maybe not??)
Config.in in net/irda/compressors .
I compiled the kernel without any problem.
I then downloaded and compiled :
irda-utils-0.9.14.tar.gz
openobex-0.9.7
openobex-apps-0.9.7
So far so good.
As I read from (outdated) IR_howto and this mailing list I made
crw-rw-rw- 1 root root 161, 0 Feb 23 04:34 /dev/ircomm0
crw-rw-rw- 1 root root 161, 1 Feb 23 04:34 /dev/ircomm1
crw-rw-rw- 1 root root 161, 16 Feb 23 04:34 /dev/irlpt0
crw-rw-rw- 1 root root 161, 17 Feb 23 04:34 /dev/irlpt1
and added to /etc/modules.conf the following lines:
# IrDA over a normal serial port, or a serial port compatible IrDA port
alias tty-ldisc-11 irtty
# IrCOMM (for printing, PPP, Minicom etc)
alias char-major-161 ircomm-tty
I then inserted the various relevant modules:
modprobe irda
modprobe irtty
modprobe ircomm
modprobe ircomm-tty
output of lsmod is:
ircomm-tty 30704 0 (unused)
ircomm 13376 0 [ircomm-tty]
irtty 7536 0 (unused)
irda 137264 0 [ircomm-tty ircomm irtty]
on syslog:
Feb 27 01:17:21 localhost kernel: IrCOMM protocol (Dag Brattli)
Finally I'm able to issue
' irattach /dev/ttyS2 -s ' and not the apparently deprecated
irmananger ... (as I thought was correct following the IR_HOWTO)
on syslog I obtain
Feb 27 01:19:35 localhost kernel: IrDA: Registered device irda0
Feb 27 01:19:36 localhost irattach: executing: 'echo 1 > /proc/sys/net/irda/discovery'
Feb 27 01:19:36 localhost irattach: Starting device irda0
Feb 27 01:19:36 localhost irattach: executing: 'echo mycomputer >
/proc/sys/net/irda/devname'
So far everything is going as expected.
I issue a 'irdadump' with my Ericsson R320s with InfraRed turned on in
front of my laptop ir-eye
I obtain output as
...

the command /sbin/ifconfig irda0 results in

So I try with the Palm. I get a slightly different output from irdadump
but once again without any successfull discovery

I did various other attempts with irobex (but I figured that was not
critical, since really nothing get recognized at a lower level, is this
true ?)
I tried also to increase debugging with
echo 1 > /proc/sys/net/irda/debug
without much success.
The Palm and Phone IR work perfectly either among them, or to
(sigh) W95.
I'm willing to experiment more, but I would like some hint
before getting _completely_ frustrated.
Thanks for your time
