 |
|
Update: The IBM Thinkpad R31 - series seems to use a smartlink chip (not lucent, how the handbook told me).
so i don't need to install ltmodem, but slmodem. the version in portage is 2.9.10 and it seems to work - wvdialconf finds the modem
(i have no dialtone, but i will try it with another cable)
this post helped me :
[url]https://forums.gentoo.org/viewtopic.php?t=198496&postdays=0&postorder=asc&start=25 [/url]
</update>
hi all together,
i try to get the winmoden in my IBM thinkpad (r31-series)to work:
(kernel 2.4.27)
i emerged ltmodem, and had a look at the post-install-infofile
(/usr/share/doc/ltmodem-8.26_alpha9-r1/html/post-install)
i followed the steps one after the other
- i logged in as root
- i made a killall -HUP devfsd
- executed wvdialconf (here, my computer tells me that there is no /etc/wvdial.conf)
after that i tried to get a connection with kppp.
i ran the 'modem-test', but i got the message that there is no /dev/modem
after that, i had a look if the modules are loaded properly -
i unloaded them, and re-loaded the lt-modules with 'modprobe lt_modem'
i got some error-messages :
| Quote: |
warnig: loading /lib/modules/2.4.27ltmodem/ltmodem.o will taint the kernel : non GPL - license
module lt_modem loaded with warnings
/lib/modules/2.4.27/ltmodem/ltserial.o : init_module ; no such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters you may find more infos in syslog
/lib/modules/2.4.27/ltmodem/lt_serial.o : insmod lt_serial failed
|
i looked in /var/log/messages - but there was no infomation about any error 
i did not know what to do now
i looked in the devfsd.conf - but there i found nothing about a modem, i found some entry in
/etc/devfs.d/ltmodem
| Quote: |
REGISTER ^tts/LT0$ CFUNCTION GLOBAL Symlink $devname modem
UNREGISTER ^tts/LT0$ CFUNCTION GLOBAL unlink modem
|
so , can anyone help me what i have to to next ??
thanks in advance

Ltmodem is complex due to a bunch of issues, but can work well.
What you've shown so far tells me that the modules aren't loading so of course your modem doesn't work.
We need to find out why the modules aren't loading.
The ltmodem script does some diagnostics when it builds. It saves that to a file called BLDrecord.txt which portage stores in your doc dir. It is basically the same as what scrolled by on the screen when you built ltmodem.
Post your BLDrecord.txt.... |

okay, i have the laptop back, and can have a look...
i searched for the BLDrecord

It used to work with 2.4.2x kernels, but for a long time I've been using only 2.6.x and I can confirm that it works for those kernels. Maybe you should try ck-sources 2.6.9-ck1 and the lastest version of ltmodem.

i don`t know exactly, but it seems that the kernel headers are missing ?
is that somethiong i have forgotten when i compiled the kernel ??

Try to set CONFIG_MODVERSIONS to y, rebuild your kernel, reboot and try again

Well, since you already upgraded to a 2.6 kernel, lets work with that. You need to use the latest ltmodem which is currently masked, so do the following:
1. make sure /usr/src/linux points to the current sources:
| Code: |
cd /usr/src
rm ./linux
ln -s /usr/src/linux-2.6.8-gentoo-r3 linux
ls -l /usr/src
|
2. Then allow portage to use ~x86 ltmodem
| Code: |
echo "net-dialup/ltmodem ~x86" >> /etc/portage/package.keywords
|
Then emerge ltmodem again, this time it should emerge -r3
To load modules:
Send the new messages, if this doesn't work for you |

okay, i compiled my kernel with
| Code: |
'CONFIG_MODVERIONS=y'
|
(the updated config-file can be found here)
(some other error occured - i cannot use the trackpoint any longer - but i will try to fix this later)
after that, i followed the steps suggested by flybynite, and emerging of ltmodem was succesful.
i was not able to 'modprobe ltserial', but there is a module called 'ltmodem' which was loaded properly:
dmesg output is:
| Code: |
atkbd.c: Spurious ACK on isa0060/serio0. Some program, like XFree86, might be trying access hardware directly.

ltmodem: module licence 'Proprietary' taints kernel.
Loading Lucent Modem Controller driver version 8.26
|
after that i did
| Code: | | wvdialconf /etc/wvdial.conf |
to get a configuration-file, but thats not working:
| Code: |
[:Tito ~ # :] wvdialconf /etc/wvdial

...

Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?
Please read the FAQ at http://open.nit.ca/wvdial/
|
i found some entries for ltmodem in /etc/modules.d/ltmodem:
| Code: |
alias char-major-62 ltmodem
alias /dev/tts/LT0 ltmodem
alias /dev/modem ltmodem
|
and in /etc/devfs.d/ltmodem
| Code: |
REGISTER ^tts/LT0$ CFUNCTION GLOBAL symlink $devname modem
UNREGISTER ^tts/LT0$ CFUNCTION GLOBAL unlink modem
|
a look in /dev offers me NO /dev/tts/LT0, and NO /dev/modem
does anyone have a suggestion what to do next ?

ltserial is essential to get it working.
try to do a depmod -a and modprobe ltserial again.
try to find out if there is a ltserial.ko file in /lib/modules/2.6.xx

susi.
I have a similar problem, and so far now I've found out that my modem, it's not supported. 
to dinf out you have to do a lspci -v, then a lspci -nv and see the vendor and device id.
You can also download and run scanmodem, wich wil automatically tell you if your modem is supported.
Go on and read the following thread, I've explained it all much better there.
https://forums.gentoo.org/viewtopic.php?t=266901&highlight=modem+slmodem

have a look at part of the output of scanmodem

Vendor 11c1 corresponds to Lucent Technologies or subsidiary Agere Systems, Inc.

2) soft modem Subystem chips requiring identification through codec readouts.
Class 0703: 11c1:048c is still NOT supported under Linux, as of 2004_Dec_14
It is a "software" modem without a digital signal processing (DSP) chipset.
The ltmodem drivers from http://ltmodem.heby.de resources for DSP modems do NOT provide support,
A dialout terminates with "No Carrier" or a Hang if usage of the ltmodem drivers is attempted.
|
you can get the "11c1:048c " id with lspci -v and lspci - nv |
