PostPosted: Mon 19 May 2008, 09:20    Post subject:  How to use USB dialup modem with wvdial.conf  

wvdial.conf when accessing "modem= /dev/usb/ttyUSB0 will not read more than /dev/usb deep into the directory. The error message gives cannot access /dev/usb: this is a directory. To get the usb modem to work you have to delete /dev/modem (rm /dev/modem) and symlink /dev/usb/ttyUSB0 to /dev/modem (ln -s /dev/usb/ttyUSB0 /dev/modem)
Then open up /etc/wvdial.conf and change the modem line to read "Modem= /dev/modem". (instead of "Modem=/dev/usb/ttyUSB0") Then start Pupdial and it should connect if your usb is a ttyUSB0 modem. I have this setup in /etc/rc.d/rc.local
----------------
rm /dev/modem
ln -s /dev/usb/ttyUSB0 /dev/modem
---------------
When booting it works now
I have also found in both puppy 4.00's (2.6.21 kernel and .25 kernels) that the modem doesn't stay online it dials in but I cannot get a connection. On further experimenting the modem stays online by changing the connection speed from 57600 (default) to 115200.

PostPosted: Mon 19 May 2008, 10:16    Post subject: Setting /dev/modem  

russ,
Thanks for posting this info. However, the modem-initialization scripts should do that for you, if the USB modem is plugged in before booting. Hotplugging has not yet been fully addressed.

If you did have the modem plugged in at boot-up, then the failure of the script to set /dev/modem appropriately could be considered a bug. Otherwise, please try that and report any failure in the Bugs forum, Puppy4 DINGO. I have focussed on getting modems to be detected correctly, so you could help me straighten this out. In your posting, please include details of your modem and computer setup.

Thanks.
Richard

I have the usb modem plugged in at bootup and it properly links the modem to /dev/usb/ttyUSB0 in the wvdial.conf setup but the Pupdial does not read to the /dev/usb/ttyUSB0 file...it will only get to /dev/usb and gives the above error message "/dev/usb is a directory". It will however read to the "2 directory deep" file /dev/modem. I am guessing that this is correct because everything works fine when accessed to this 2 deep directory.
I have a Toshiba M35x-s311 laptop (pentium-m centrino, 768mb memory using puppy 3.01 liveCD with setting on a usb thumb drive. My modem is a Actiontec EX560LKU external USB/Serial 56k hardware setup.
I have tried it also on the new Puppy 4.0 using both kernels (2.6..21 and .25)and it tries to access the modem the same way on all three setups (which includes this 3.01 setup). However I can dial out (after making the first post adjustments) using both 4.0's but cannot establish a connection like I can in 3.01 which maybe another bug. I posted most of the above in the "Dingo 4.0 bugs" site.

Thanks for the details. What does the "USB Interfaces" display in PupScan show? Does it list the modem but with module "unknown"? Please post the USB-Interfaces info. Also post the content of /tmp/bootsysinit.log, which could hold a clue.

I expect the driver/module name is pl2303; the script for it sets up /dev/modem as /dev/usb/ttyUSB0. My guess is that Puppy doesn't detect the modem and associate it with the driver. The script would be /etc/init.d/Pl2303, but it probably will not be there.

I understand that you:
1. boot up with it plugged in
2. run the two commands you mentioned
3. edit wvdial.conf to set "modem=/dev/modem"
4. run pupdial, etc.
Anything else?

Does pupdial show anything other than "ATZ" in the initialization-string fields?
I see with google that people have had trouble with this modem. They seem to need to "reset" it for each boot-up, whatever that means.

Please confirm or counter my assumptions above, to get a "handle" on this. Please run without your commands in rc.local, to avoid confounding things, possibly with pfix=ram and a new pupsave. Thanks.
Richard

Thanks, russ, for the listings.

Is the /tmp/bootsysinit.log listing from puppy 4.00? I ask that because I expect to see "loading modules for pci interfaces" followed by "loading yenta-socket". Do you have anything in the PCcard slot?

The loading of "slamr" indicates your built-in modem is a SmartLink, which I would expect to work. On the chance that pupdial could be confused by the presence of two modem drivers, please blacklist slamr, using the system>bootmanager.

For the USB modem, it appears that it is detected and set into /dev/modem OK. But wvdial itself, within pupdial, does not seem to like more than two levels in "modem =", as you have already concluded. Let's try an easy fix, to see if it is sufficient. Please edit a script then reboot (saving to a pupsave).

Edit file /etc/init.d/Pl2303, to change line 14 into two lines:
Code:
Old line 14:   ln -snf usb/ttyUSB0 /dev/modem
New lines 14 &15:
 ln -snf usb/ttyUSB0 /dev/ttyUSB0
 ln -snf ttyUSB0 /dev/modem


That should satisfy wvdial; maybe blacklisting slamr might help in connecting (fingers crossed).

Could you also post the "PCI Interfaces" list from PupScan (before you blacklist slamr), so I can check on the Smartlink modem. In what way does it not work, if you leave the USB modem unplugged at bootup? (USB takes precedence.)

I may be delayed in responding, due to a busy day tomorrow.

russ,
Good job! Thanks for trying it. The login speed might be something to fix. I will have to defer that until the end of the month, as I will be away.

Another bug to report! Thanks to your help. Could you re-title your initial post to report a bug? Specifically that PupDial cannot connect to device /dev/usb/ttyUSB0.
Richard

Moderator: Please move this thread to the Bugs forum, since it includes a fix for puppy 4. Thanks.

Barry: Please consider this a fix for script Pl2303. The same type of correction should be made to other scripts that set /dev/modem to a three-level-down device. Thanks.

Dalderton,
I am not an expert on modems but I do know that some USB modems are "software" modems in that very little hardware (no processor) is used and more software is used to run modem. These are usually called winmodems. Linux has a hard time using these types of software modems. I tried to google your modem and I found this page on a Roadster II 56 USB modem (about 20 lines down from beginning comments)
http://www.qbik.ch/usb/devices/showdev.php?id=52

edit:
You might try the "modem-wizard" located in /usr/sbin/modem-wizard. Just click on the file and it should start the program. From the lineup of the setups to use try the "ttySL0" selection then "USA" for "Choose country" (if from USA) then "USB" under "Choose type of smart-link modem". If success then "save"

Hi Dennis!
Welcome to the "usb-modem workshop."

If you suspect your modem uses driver pl2303 (Pl2303 is the name of its modem-initialization script.), then you need to make the same change that russ made, described in my post of May 19, above. That allows PupDial to work with it. With that fix in place, we can work from there. First, please post the content /tmp/bootsysinit.log and the listing provided by PupScan for USB Interfaces. That may tell us what driver is used.

russ,
[Reply moved to another thread, in response to kapper, not russ.]

Russ Thanks for the reply.I tried the Modem Wizard with no success and I think my problem is a little earlier in the sequence.It seems strange that Puppyscan sees the Modem but nothing else does. In the boot sequence the Serial modem is recognised and spoken to at some length but if I erase the wvdial.conf file and boot up with the usb modem plugged in the bootup sequence only remarks that there is no modem present.This seems to me to indicate that this is the area that needs modification.I must say here that I only know enough about this stuff to know how much I dont know.
Richard The info from Pupscan on the modem is included in my original post as is the /tmp/bootsysinit.log with the wvdial.conf file blank and the Roadster 11 56 USB modem plugged in at startup.
I tried the mods that you suggested to Russ along with his original mods with no success. My reference to the Pl2303 was because of the reference to it by Russ in his original post.I created the file shown I.e /etc/init.d/Pl2303 without really knowing why and it made no difference either.
Where now??? Regards Dennis

Dennis,
Sorry to be so dense, in requesting info you already provided. My excuse is that I have been away from the subject awhile, 3,000 miles from home and preoccupied.

I have searhed on the modem name and found old info here:http://www.qbik.ch/usb/devices/showdev.php?id=52
that indicates that the driver is "acm". Our version of that is cdcacm; at least that driver supports /dev/input/ttyACM0. However, only Rev. 3 of that modem works with linux; earlier ones are non-standard. Since your product ID is 1 higher than the one discussed, I would expect it to be at least Rev. 3.

Even if Puppy detected your modem as an "ACM" type, it would have a problem and fix similar to that russ tried with his modem. But the script Cdcacm is the one to fix. Where the "ln -snf input/ttyACM0 /dev/modem" instruction appears, it should be changed to
Code:
ln -snf input/ttyACM0 /dev/ttyACM0
ln -snf ttyACM0 /dev/modem
That will allow PupDial to handle it. (Don't bother with the modem probe; it only looks for ttyS-something.)

It appears that Puppy doesn't know about that hardware. As an experiment, try using the BootManager to load cdcacm as an additional module, to see if it detects the modem.

Currently, there is no simple way to add a USB module to the list Puppy recognizes. If Barry hasn't already done it for 4.01, I expect to implement an override scheme similar to that used for PCI hardware. But to test your modem before that, I would modify the file /lib/modules/...usb-map (something like that -- I have no access to Puppy this week, so cannot try it until the weekend) The trick would be to copy one of the statements beginning with "cdcacm" and substitute your vendor and product IDs in the second and third fields -- but first verify that it is not already there. I can set it up after I return home, if you don't want to.

I have written the above with no reference to Puppy code, so hope I got it right. I hope your modem is Rev. 3 and that we can get it to work, although the link above suggests people had trouble with it faster than 28.8k.
Richard

PS: I also found this at another site, referencing the same hardware ID as yours:
Quote:
. . NetComm (AU) .
AUS C-Tick #N367 Roadster II 56 USB, Model AM5050R3, Conexant CDC USB chipset, use "ln -s /dev/usb/acm/0 /dev/modem" (USB\VID_06EA&PID_0002) USB John Reid
So you might try substituting the following, instead of the above code:
Code:
ln -snf usb/acm/0 /dev/ttyACM0
ln -snf ttyACM0 /dev/modem
First verify that "/dev/usb/acm/0" exists.

Thanks for the info,Iwill have a play tomorrow and see what happens.
I found Pl2303 in the boot manager and installed it and the boot sequence recognised an analog modem but did not seem to communicate with the modem as the serial one does. When I used pupdial it showed a modem /dev/ttyUSB0 but said it was a directory etc I then tried the fixes suggested by you and Russ but when I tried to connect the modem flashed once and that was it. Still some progress is made. I will let you know how your latest tricks go.
Thanks again Regards Dennis
ps Incidentally some years ago this usb modem worked quite well on a version of Mandrake however it only worked on one then later it did not.
Module cdcacm sounds familiar. Regards Dennis
