Question Help needed installing internal modem

Hi everyone,

I have recently installed Red Hat 8.0 on my Toshiba Laptop. Being a , I used this wonderful forum to answer some basic questions. However I am now stuck on something and would love some help.

My laptop (like many others) has an internal modem (not PCMCIA card but actually installed within the chassie of the laptop). From what I have gathered, this seems to be a LT winmodem, where WinXP describes it as a "Integrated V90 K56 Flex Modem".

After doing some initial research here, I downloaded the latest binary ltmodem drivers (5.68) and using the readme file, I followed the instructions to install the driver within Linux.

I came across some problems after running the ltinst script (I was logged in as root and was in a terminal prompt) where I was first given the error that the ltmodem.o file could not be copied because the file or directory did not exist. After creating the /misc directory manually, this cp error disappeared, leaving the last error, "ltmodem: no module by that name".

From what I understand (I am not sure) this means that the module has not been installed properly, therefore Linux is not aware of the /dev/modem device, and so I can not use it via minicom (as recommended by the readme with the driver)

So I am stuck. I am rebooting into WinXP everytime I need to do more research, and I would LOVE it if I could be on the Internet reading and learning more about Linux.

If you can help me with this, I would be very grateful.

Check and make sure you have the linux kernel source code installed, that it is the same source code as the running kernel and that you have a symbolic link /usr/src/linux pointing to it. I will check my system by opening an x terminal and giving these commands:
[phil@uilleann phil]$ su -
[root@uilleann root]# uname -r
[root@uilleann root]# cd /usr/src/linux-2.4.18-3
[root@uilleann linux-2.4.18-3]# ls
abi      COPYING        drivers  init    lib          mm      REPORTING-BUGS
arch     CREDITS        fs       ipc     MAINTAINERS  net     Rules.make
configs  Documentation  include  kernel  Makefile     README  scripts
[root@uilleann linux-2.4.18-3]# cd /usr/src
[root@uilleann src]# ls
linux-2.4  linux-2.4.18-3  redhat
[root@uilleann src]# ln -s /usr/src/linux-2.4.18-3 linux
[root@uilleann src]# ls
linux  linux-2.4  linux-2.4.18-3  redhat
[root@uilleann src]#
I noticed that my Redhat 7.3 had a symbolic link called linux-2.4 pointing to the kernel, so I created the symbolic link I need to install the module.

Change of Plans :P


Since my last post, I spoke to a friend who told me to try Mandrake out, and with my frustrations already, I rebuilt using Mandrake.

However, same issue is still apparent. When I used your command (uname -r) in mandrake, I recieved the output: 2.4.19-16mdk. However I can't find this directory in /usr/src therefore I couldn't create the link you were talking about.

On another note, I did some more searching and found (on a file that has some drivers and also a handy scanning utility (scanPCI) which I used to see what hardware I had. I have pasted this info below. However, I am still stuck as to how to install the modem. If you or anyone else can help me I would be very greatful.

Thanks in advance,


Output of scanPCI:


By the Class 07nn: criteria, detected system PCI modem devices are:

In Linux, you get the same stuff in probably more understandable fashion with the command

cat /proc/pci

This probably won't work, but it's a common winmodem:

Conexant/Rockwell modem HOWTO

Perhaps you can find something that will help in these Google hits.

I would toss that modem in the trash and use a real modem. External serial port modems always work.

# Mandrake links
Mandrake home page
Mandrake Users website
Easy software management: Red Carpet
Maximum RPM
You didn't install the developmental packages? As root, command:
urpmi gcc

Wink Thanks

Well ... I'll read the links you gave me ... thanks for your help anyways.

PS. If I toss my modem in the trash, I'd have no laptop since it's an internal modem

Don't do that then!

You gotta serial port on that boat anchor though don'cha? That will fix you right up.

I picked one up for $14 two weeks ago. NAH na na NAH NAH

Are you sure that you know what the internal modem is ?

If it is an AC'97 AMR modem chip (often known as a Softmodem) ?

Then you want to get a Smartlink driver from this Webpage

Look in the "a local copy of the available drivers" area of the AC'97 AMR section

Even if you do not have an AMR internal Softmodem there is info + links for lots of other Intenal winmodems on this page also.

PS. I know the Smartlink drivers work with many Toshiba Laptops - but as you did not state the exact model you have I do not know if it will work with yout Toshiba Laptop ?
