cannot open dev modem no such file or directory


In Gnome ppp I get the following error
WvDial<Err>: Cannot open/dev/modem: No such file or directory

This came up after I had done some upgrades and now I cannot get Ubuntu connected to the internet. I don't know which ones upgraded - I am a newbie.

My system is a dual boot Ubuntu 7.10 and Vista

I have tried installing a new driver for the Conexant D850 56K V.90 DFVc Modem

The new driver is hcfpcimodem_1.18full_k2.6.22_16_generic_ubuntu_i386.deb from Linuxant. It is the free one. But I get the same error message even after restarting.

Please help, I am getting very frustrated.

You'll have to reconfigure gnome-ppp, there should be a drop down menu or similar where it suggests using /dev/modem, in the menu containing many /dev/tty...., select /dev/ttySHSF0 or similar instead of /dev/modem.
I never did install gnome-ppp, I use wvdial, but use kppp in Mandriva, and that's the port for Conexant HSF modem, probably the same for the HCF modem.
If you're using a Dell computer that came with that Linux distribution, you should be able to get the full speed driver from Dell downloads.

cannot open dev modem cont

Still doesn't work. When I change to the dev.ttyso I get an input/output error.

I will have to try later what I can get from Dell but being that this computer is a little over a year old and Ubuntu did not come pre-installed I am not going to hold my breath.

How do I check what modems I have in ubuntu?

Thanks

In a terminal, type: lspci -v to get information about pci bus and devices on it. Also, check the FAQ link here at linuxant for the HCF modem, pay special attention to #4, this will tell you which device the HCF modem driver creates, it normally does not use /dev/modem. Some graphical dialers like gnome-ppp or kppp do not include all the devices created by modem driver installers. But if you had it working before the update, it should be available unless gnome-ppp was one of the updates and the device node got eliminated, but I doubt it.

Below is the output of that command on my Dell XPS Gen2

Code:
00:1e.3 Modem: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Modem Controller (rev 03)
	Subsystem: Conexant Systems, Inc. Device 5423

Okay I ran the lspci -v and Ubuntu is recognizing the driver as Conexant HSF 56K Data/Fax Modem. Does this make a difference as Vista is recognizing the Modem as a D850 56K V.90 DFVc Modem and I have been dealing with hcfmodem?

Anyways I tried the free HSF driver from Linuxant and still the same error. I also tried the other suggestions and got nowhere.

Also, in the directions for installation it says to uninstall previous HSF or HCF drivers using rpm command. My terminal is saying that the command is not available (i think) and being that I cannot get Ubuntu online I cannot tell it to download that command.

I would like to upgrade Ubuntu to the latest stable distro, should I upgrade now and then continue to work on this problem?

Thank you for your help.

To remove installed packages, go to System/Administration/Synaptic_package_manager and scroll down to hcfpcimodem and right click it, select "Mark for complete removal", then click apply at the top to remove it, you may have to remove the HFS one also if you installed it. Then try to install the HFS driver that matches your current running kernel. You have to make sure you download the one that matches your current running kernel, to see which kernel you are using, type in a terminal: uname -r.

For example, the hcf driver you posted in your first post is for the 2.6.22_16_generic kernel, if linuxant doesn't have a package matching your current running kernel, you have to download the generic package called "hsfmodem_7.80.02.03full_i386.deb.zip", you'll need linux-headers package from CD installed to compile the driver to match your kernel. There is a link at the top of the list of Ubuntu drivers called "generic packages with source" to find this source package, but you should be able to find the one that matches your current kernel.

Sorry to not have gotten back sooner but life gets in the way.

Anyways the problem is still there.

I have downloaded and installed the modem driver called for by scan modem. I have also tried other similar drivers for my kernal as the conexant driver download page has some mislabeled driver files.

I have also tried the other suggestions and got nowhere.

Could it be wvdial having a problem? I have tried going to the website listed in scan modem for wvdial and I don't get anywhere. Where could I download wvdial from?

Any other suggestions?
Thank you.
