I just bought a Dynalink 1456VQH-T4 with Agere/Lucent chipset so I can use the Net on my SUSE 9.2 Pro box and now it wont connect as it cant find the device (on connection). Drivers installed fine but as soon as it trys to connect it cant find it. Is this SUSE having problems setting it to a /dev/ ?

Is there a way to fix this?


(If it helps I have a ASUS A7N8X-X mobo, with Athlon 2500+ and 512MB ram and the modem is located in (PCI Slot 7 (PCI bus 1, device 9, function 0)) as stated by Windows which it works fine in.)

Hi Mercuryone,

Which drivers did you install, and from where?

Hopefully you have the "ltmodem" driver package. If so, it should have created special device files under /dev/ttyLT0 or /dev/ttyLTM0. Depending on your distro, you may need to explicitly create a link to /dev/modem.

Another possibility is that you are using an unsupported Lucent modem (not all are supported). Have you tried running "scanmodem"?

Lots more information may be found here:

I'm using the drivers that came with SUSE 9.2 Pro.

And it did create the special device files at /dev/ttyLT0 but said it was unable to find the device on trying to dial up.

Got any suggestions?

Hi Jason,

Here are a few things to check:

1) you should have a /dev/modem link to /dev/ttyLT0. Execute this command:

ls -l /dev/modem

You should get something like this back:

lrwxrwxrwx 1 root root 16 2005-09-28 15:35 /dev/modem -> /dev/ttyLT0

If you don't, this is probably your problem. An easy way to fix is to use YaST to configure /dev/ttyLT0 instead of /dev/modem. Look for "modem" under the Hardware section. Pick your modem, then select "edit", then change "Modem Device" from /dev/modem to /dev/ttyLT0.

2) the special kernel modules for the modem should be loaded. Execute this command:

/sbin/lsmod | grep lt

You should lines for lt_modem and lt_serial. If not, the driver has not been successfully installed.

3) you should have a supported Lucent/Agere modem. Not all of them are supported - that's where "scanmodem" would be helpful from the link I posted earlier. Another way to find out is to do this:

/sbin/lspci -n -d 11c1:

You should see something like this:

0000:00:06.0 Class 0780: 11c1:044e (rev 01)

Take note of the "device" number, which is 044e in my example. If this command gives no output, or the device number is not in the ranges 0440-044f or 0450-045c, you do not have a supported Lucent/Agere modem.

Good luck,
Jeff Trull
