I have an Acer laptop (Extensa 4420) with Ubuntu 8.04. The laptop has
a built-in modem, as well as a pc card slot, for which I have an old
modem (which works under windows, and which worked for a friend of
mine on a different laptop under some flavor of linux). I can get
neither to work, and would greatly appreciate your assistance in
getting one of them to work. I'll first give an overview of what I
tried so far, and then more details in Parts A and B below.
Best,
Nikolaus
----------------
The built-in modem is identified under windows as follows:
Under Vista, "Phone and Modem Options" shows that the built-in modem
is an Agere Systems HDA Modem. Under Properies, Diagnostics:
Hardware ID: HDAUDIO\FUNC_02&VEN_11C1&DEV_1040&SUBSYS_10250100&REV_1002
So Vendor ID seems to be 11C1 and Product ID 1040. Accordingly,
I tried to get this modem to work following the instructions at
http://linmodems.technion.ac.il/packages/ltmodem/11c11040/,
but had no success. MORE BELOW IN PART A.
The laptop has also a pc card slot, and I have an old pc card modem
(ZOOM V.92 PC Card Model 3075, the one with an "L" in the serial
number). This modem works under windows (vista), and reportedly
worked for a friend on a different laptop on some version of linux. I
also cannot get this modem to work: The modem is found using
"pccardctl status" or "pccardctl info", "bound to driver "serial_cs"".
But wvdialconf only finds the modem some of the time, and I have not
been able to figure out what causes it to find it or not.
When it is found, the connection speed between wvdial and the pc card
modem is usually extremely slow. I verified this in kermit, where the
command "at&v" takes forever (unless I keep hitting return, upon which
the modem reports back its output about half a line at a time for each
"return").
Finally, the few times I got the connection speed between wvdial and
the modem to be fast, the modem dials correctly and establishes a
connection with the internet service provider, and gets to the point
where it receives the login prompt. Then wvdial submits my username
(souzavonessen@xxxxxxxxxx), which is echoed, however, by the modem as
"ooeeoer.Net". Then nothing works anymore, and the connection breaks.
MORE BELOW IN PART B.

PART A - The Agere Soft Modem:
- http://linmodems.technion.ac.il/packages/ltmodem/11c11040/linux-image-2.6.21.0-22_2.6.21.0-22_i386.deb
didn't work: When I try to boot into this kernel it fails (freezes
while booting), both with and without kernel boot option "pci=noacpi".
I am ignorant; this is maybe because my CPU is an "AMD Athlon
64X2 Dual-Core Processor TK-55 1.80GHz". If so, how do I install
"kernel-2.6.21.0-22.i686.rpm", and what do I have to do to make this
work?
- I also tried to follow the instructions in
http://linmodems.technion.ac.il/packages/ltmodem/11c11040/agere-driver-1.0-10dd.txt
I made sure I have the kernel headers installed (information from
synaptic package manager) for my version of linux,
2.6.24-18-generic. "make" resulted in various warnings (listed a
few lines down), the rest of the installation process seemed to
work. But "sudo wvdialconf" either doesn't detect the modem, or
dies with last output line of
"Modem Port Scan <*1>: S0 S1 S2 S3 Segmentation fault".

Here is some more information for the pc card modem, in case it helps:

- Output of at&v under kermit
- Various examples of wvdialconf finding the pc card modem or not
- The output of wvdial when (by chance?) there is a fast connection

conecting to the internet service provider).

If another modem card has not been detected, then possibilities are:
1) A Conexant modem chip is present on 1002:4383, as Conexant chips
are frequently not detectable by ALSA diagnostics
2) The modem may be of the older non-PCI Controller Chipset (hardware) type.

The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.2.3
and the compiler used in kernel assembly: 4.2.3
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.2
linuc_headers base folder /lib/modules/2.6.24-18-generic/build
However some compilations and executable functions may need additional files,
in the FileNames.h (so called kernel "h"eaders) collection installed in /usr/include/ .
For martian_modem, additional required packages are libc6-dev (and for Debian/Ubuntu,
linux-libc-dev). The also required headers of package libc6 are commonly installed by default.
Compiling hsfmodem drivers does require linux-libc-dev and libc6-dev packages, for kernels 2.6.24 and later versions.
In not included on your install CD, search for them at http://packages.ubuntu.com
or comparable Repository for other Linux distros.
When compiling ALSA drivers, the utility "patch" will also be needed.
If a driver compilation fails, with message including some lack of some FileName.h (stdio.h for example), then
Some additional kernel-header files need installation to /usr/include. The minimal additional packages are libc6-dev
and any of its dependents, under Ubuntu linux-libc-dev
If an alternate ethernet connection is available,
$ apt-get update
$ apt-get -s install linux-kernel-devel
will install needed packages.
For Debian/Ubuntu related distributions, run the following command to display the needed package list:
Otherwise packages have to be found through http://packages.ubuntu.com
Once downloaded and transferred into a Linux partition,
they can be installed alltogether with:
