[7.04] How can I detect my IRDA hardware?

Put the following in Terminal
sudo apt-get install irda-utils
Hope that helps.

Don't think so, even if it's been a good hint:

Couldn't find Winbond superI/O chip.

Have you checked to see if the module has been loaded?

After the reboot I see:

...
[ 17.105742] irda_init()
...
[ 35.002115] sirdev_get_instance - ttyS1
[ 35.006133] irtty_open - ttyS1: irda line discipline opened
[ 36.013925] irlap_change_speed(), setting speed to 9600

Nonetheless the findchip still says "no chip found".
lsmod says (among other things);

irtty_sir 9600 2
sir_dev 17156 1 irtty_sir
irda 201276 2 irtty_sir,sir_dev
crc_ccitt 3072 1 irda

How can I check whether everything is working?

How do you turn Irda on in Windows?

I have no idea. I'm not running Windows on my PCs since 2001.
I've just tried this:

HI.
I've done an irattach on /dev/ttyS1, turned on my phone's IRDA and then:

# irdadump

So it seems to work, even if I cannot say precisely how to activate and how to deactivate IRDA.
Some more time and maybe fun and I'll get rid also of this.
Many thanks for the help!

Thanks Felix Heinonen, that solved my question.

I also have an IrDA related problem.
I have an IBM Thinkpad T42, and I don't know how to enable the IrDA port.
I have tried the hints in this thread, but that did not help me.

When I type: sudo modprobe lirc_sir
I get: FATAL: Module lirc_sir not found.

I get the same "module not found" for all the modules I have tried.

I hope this help you out:

By the way, "man irdattach" has lots of interesting information.
