Just tried the 8.31a2 drivers and it still fails. The only thing I see
that might be causing it is the version mismatch for gcc and binutils. I
thought these drivers support the 2.6 kernel but there's no mention
anywhere (someone correct me if I'm wrong).
I'm including BLDrecord.txt and ltrecord.txt. Maybe I'm missing something.

======= Fedora code changes =======
SmartLink slmodem-2.9.n and Intel537 drivers are already Fedora competent.
For usage of winmodems with the kernel-2.4.nn Fedora releases
a change in the serial-like driver code of WinModems is necessary.
See for guidance: http://hepunx.rl.ac.uk/~wmurray/pctel/pctel.html
Basically , the line:
if ((tty->count == 1) && (state->count != 1)) {
should be changed into:
if (atomic_read(&tty->count) == 1 && state->count != 1) {
This works in the ltmodem code too. See
http://linmodems.technion.ac.il/archive-third/msg02360.html
An error about "rs_close" during compiling is a signature that the fedora fix is needed
redhat is not yet providing pre-compiled drivers for WinModems

Lucent/Agere_Systems(AS) DSP chip modems (but Not the AMR of soft PCI chipsets)
are supported by the the resources of this kit.
AS maintainer S. Sarkar develops the code on a Red Hat Linux test bed.
The lt_serial.o Serial Interface module comes under GPL and is Open Source.
The lt_modem.o code is entirely proprietary, though partially Open Source.
Adaptation to ongoing changes in Linux source code is enabled by the Open Source components.
Critical AS proprietary information is pre-complied in ltmdmobj.o,
whose constituents are functionally not affected by minor Linux source code changes.
Volunteer maintainers periodically receive code updates from AS.
Through the contributions of Many described in CREDITS, there are
enhancements in utility, ease of installation and documentation.
Mark Spieth initiated this ltmodem compiler kit series.
Chris Hebeisen introduced the Configure implementation, bringing Newbie friendliness.
Marv Stodolsky is culpable for the verbose messaging.
Within DOCs/, Ltmodem.html has URLs to many particular usage cases.
Volunteers assemble the ltmodem-version.deb and
ltmodem-version.rpm Installers for the User Community as Linux source code evolves
utiliizing the resources of this compiler kit series.
If new to compiling, please first run: utils/ksp.sh
to set up your kernel-sources properly. The kernel-source package as installed
does NOT in general match an installed kernel, but one of several alternative kernels.
Thus with a niave usage, all could be completed well technically.
BUT the installed drivers might not be compatible with your kernel,
of even reside in the needed /lib/modules/Kernel_Version/ tree.
This compilation process is likely Not necessary to work through,
if the only need is modem drivers matching the standard kernel of the
following Linux distributions: Debian, Red Hat, Mandrake, SuSE and Connectiva
Volunteers have already compiled most standard drivers.
Those available as of this 8.31a2 release are embedded in utils/scanmodem,
and any compatible with your System requirements will be later listed.
They are available for download as ltmodem-version.rpm and
ltmodem-version.deb Installers from a repository, http://ltmodem.heby.de
If your System can use one of these Installers, you will be informed below.
The compiling process is a learning experience for Newbies.
We strongly recommend that you DO learn it sometime.
But getting on the Internet under Linux should have first priority.
This kit provides several diagnostics aids and good documentation.
Continuing will do no harm. Useful diagnostic information
on your system will be written to BLDrecord.txt,
with direction to documentation if a failure occurs.
At a minimum, Do keep the DOCs/ and utils/ folders and become familiar
with the resources therein.
=================================================================
This is the version 8.31a2 of the compiler + installer kit
8.31 corresponds to the version of the core Agere Systems DSP code.
a2 designation that follows reflects NO improvement in DSP code.
Rather peripheral driver, added diagnostics and installer improvements
are reflected. They are progressively implemented as Users report problems
or the Linux kernel evolves.
The modem drivers will serve with Linux kernels beginning with 2.2.2, the current
2.4.nn series, and the 2.5.nn development kernels.
However support was broken in the early 2.4.n-test series.
When there is a Red Hat 2.6.nn release, AS will then update the code
If your PC is being well served with this 8.31a2,
there is NO Benefit in using a more recent version
until there is an update in the Agere driver code, say 8.26 to 9.00.
But if the driver installation for a new kernel should in some way fail,
please do download the most recent ltmodem-VER.tar.gz
before sending a query to discuss@linmodems.org,
because the problem may already be solved.
This build_module script only compiles drivers,
with their installation managed by subsequent commands.
Thus ./build_module can be rerun for education or amusement,
without as yet committing changes to your System.
=================================================================
All should work automatically for most Linux installations/distributions,
IF a complete kernel-headers/ folder is available:
through a symbolic link: /lib/modules/KernelVersion/build --> PATH_to/kernel-headers/
at the classical /usr/src/ position.
Otherwise a symbolic link will be necessary:
ln -s PATH_to/kernel-headers/ /usr/src/linux
Read DOCs/Compile-properly.txt and 1ST-READ if an explanation is needed about kernel-headers.
To compile modules for a kernel other version than 2.6.5-1.358, such as version 2.2.17-3test, use syntax:
./build_module 2.2.17-3test
where the version.h in the kernel-headers/ folder has 2.2.17-3test
If desirable to make a record for trouble shooting purposes,
Abort with Ctrl-C. Then the process can be recorded to ltrecord.txt :
./build_module | tee ltrecord.txt
====================================================================
Diagnostic information is progressively being written to BLDrecord.txt .
Often, contents of BLDrecord.txt will aid in solving a problem.
The Linux distribution is: redhat, Fedora Core release 2 (Tettnang)
