[irda-users] Problem with the act200l driver

[Sunny P. <su...@ya...>]

Dear Mr. Tourrilhes,

    Hi, my name is Sunny Pan, I'm an honours year
student in Monash University, Melbourne. I'm currently
doing a research project which is about IrDA tunneling
over a TCP/IP network. To support the research, my
school has provided an IR dongle which is Actisys
200L. Since the project involves modification of the
lower IrDA layer, Linux has been chosen due to its
open source nature.

    However, I'm a novice in linux so that I don't
really familiar with the procedure of installing the
drivers. What I've done was I installed RedHat Linux
7.2. Since it doesn't come with the act200l driver, so
I downloaded the newest kernel 2.5.22 which has the
act200l driver included. I updated the kernel and
everything seems fine, except the adaptor doesn't
transmit anything.

Here is the step I went through:
First method(Embedded into the kernel)-
1. I configured the IrDA stack(with irtty,
irport...etc) and the act200l driver(only) as the part
of kernel.
2. Kernel has been compiled and no errors found.
3. Linux booted without any problem
4. I started the irda service by entering "service
irda start". And the status is ok.
5. The dongle had the lights(the transmitter) on.
6. Problem here, I ran "irdadump", trace lines have
been shown but nothing has been detect when I point it
to mobile phone, laptop, PDA....

Second method(Make it as a loadable module)-
1. I configured them as module
2. No problem on compilation
3. I edited the modules.conf by adding the following
lines:
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
alias irda-dongle-10 act200l
options irport io=0x3f8
4. Booted without any problem
5. I loaded the module by entering "modprobe act200l"
and when do the "lsmod", it shown:
Module         Size   Used by
act200l        1584    0  (unused)
irda          93456    0  [act200l]
6. then I do "irattach /dev/ttyS0 -d act200l -s 1"(I
confirmed it is connected to COM1(ttyS0) and the io is
0x3f8, with irq=4) and lsmod shows:
Module         Size   Used by
irtty          5904    0  (autoclean)
act200l        1584    0  (unused)
irda          93456    0  [irtty act200l]
7. Now the light is on.
8. Problem here, running irdadump this time however,
is even worse. It didn't show up any trace line.


    I also attempted so many methods but nothing was
work. The procedure I mentioned here is what I believe
the correct steps(theoretically) that should make it
works.

    It really makes me headache because I did make the
irda running smoothly on my toshiba laptop with
toshoboe driver. However, this time when I try to do
it on my desktop with the Actisys 200L, I cannot make
it even I spent lots of time on it.

    I'm so sorry for disturbing you but please help me
because I couldn't find anyway that is better than
asking the driver developer directly(I also sent this
email to the act200l author, Mr Shimizu as well. And a
carbon copy to the mailing list of irda). I tried to
look for help documents on the internet but there is
nothing about the act200l driver, and I'm now really
feel exhausted about it. However, problem is this is
an important part of my research project that I cannot
give it up.

    I would really appreciate if you can help me to
get rip of  this problem. Thank you very much!

Regards,
Sunny Pan
