Conexant chipset modems

Conexant chipset modems section
--------------------------------

Vendors 14f1 is Conexant, inheritor of the former vendor 127a Rockwell modem
technology. There are also Conexant chipsets in some modems from vendors:
158b Allied Data Tech.,
1024 Zenith
141a Apache Micro
148d Digicom Systems.

Linux drivers for Conexant chipset modems are provided ONLY through
http://www.linuxant.com/drivers. The HCF chipset modems have a dsp
(digital signal processing) chip, while the HSF lack a dsp and
this function is performed by the CPU under software direction.
For 2.4.n kernels, installation may require a patch variable: cnxinstall --patch

For a crash issue with the 2.6.16 kernel, please make sure that your
kernel was not compiled with the CONFIG_4KSTACKS option is not set as
the HSF modem driver is known to requires more than 4K of stacks in a
few cases. The are several alternate kernels supporting hsfmodem
available at http://www.linuxant.com. Look for their Link/URL on the
page with your needed hsfmodem package.

To get software, go to http://www.linuxant.com/drivers
-Find the HCF or HSF menu in the left part of the screen.
-Read README.
-Read INSTALLATION.
-Click DOWNLOAD.
-Accept conditions.
-Find text: "You can download HCF (or HSF) modem packages from the driver
download page." and click there.
-Look for your distribution, your processor, and your kernel.
-Download the matching file.
-Read again and, if you do this under Windows, print the installation
instructions matching the kind of driver file which you downloaded.
-Now just follow these instructions.

http://www.linuxant.com/drivers/hsf/downloads-patches.php has patches
that may be necessary for recent kernels.

A detailed software installation example is provided at:
http://linmodems.technion.ac.il/archive-fourth/msg00350.html

After loading of HSF drivers, there will be selective displayed by command:
# /sbin/lsmod | grep hsf
with an output like:
-----------
Module Size Used by Tainted: P
hsfich 119116 0 (autoclean)
hsfserial 26388 0 (autoclean)
hsfengine 1126348 0 (autoclean) [hsfserial]
hsfosspec 35328 0 (autoclean) [hsfich hsfserial hsfengine]
---------
plus many others not modem related.
While drivers are pre-compiled for some Linux distributions,
the installation of the HCF/HSF packages DOES in general require kernel-source/
preparation, as described in Modem/DriverCompiling.txt.

There is good support from Linuxant.com, but first gather data.
In a terminal
# su - root or prefix commands with sudo for Ubuntu related distributions.
hsfconfig --dumpdiag
If this command crashes your machine, please try instead:
hsfconfig --dumpdiag --noprobe
Send the hsfdiag.txt located in the folder /tmp/
to MODEM.SUPPORT@linuxant.com

There is a conflict between modules snd-intel8x0m and hsfmc97ich.
The snd-intel8x0m Must be loaded first or the system may hang upon hsfmc97ich insertion.

Rafael Espindola has ported old version
5.03.27 driver code to 2.6.12. This is an Experts ONLY resource with current
information at http://www.ubuntuforums.org/showthread.php?t=180632

From http://www.linuxant.com/drivers,
get package(s) with 2.4.21_47.EL.cern included in the filename.
If such a package cannot be found, get the generic package,
for which compiling drivers will be necessary.

Copy the package to your Linux partition. Unpack with:
unzip *.zip
Under root/admin permission, install with package with
your distributions installation tools.
Should the modem hardware not be a Conexant type,
the installation will ABORT with an informative message.

Continue with any output instructions. Following a successfull installation,
The modem should be detected during the root/admin command:
wvdialconf wvtest
Edit your personal information in with:
$ gedit wvtest
See details on dialout usage in Testing.txt
