Modems with Lucent/Agere DSP chipsets
--------------------------------------
For Lucent/Agere/Xircom modems with DSP (digital signal processing) chipsets
http://phep2.technion.ac.il/linmodems/packages/ltmodem/kernel-2.6/martian/
has the support packages and information for 2.6.n kernels. In Alexei Chentsov's
new martian approach, the overall support is two component:
1) The driver loaded onto the running kernel, martian_dev, is Open Source;
2) The proprietary and closed source component from Agere Systems, ltmdobj.o,
is compiled into a martian_modem helper application.
AMD x86x-64 processors are supported though only in 32 bit mode.
Beware that the martian_dev mostly provides low level contact with the
hardware. The martian_modem provides higher level COMM functions and
MUST be running throughout a dialout session. The modem port is in the
dynamically created /dev/pts/N family, with symbolic link creatd by
the martian_modem
/dev/ttySM0 -->/dev/pts/N
Usage of these ports requires that a line:
Carrier Check = no
be added to the configuration file /etc/wvdial.conf
See the file wvdial.txt for details on this usage.
For martian concept details see: http://martian.barrelsoutofbond.org
To automate martian_modem action upon martian_dev loading,
the following SINGLE line can be added to one of the files /etc/modprobe*
or to a new file /etc/modprobe.d/martian
install martian_dev modprobe --ignore-install martian_dev ; /usr/sbin/martian_modem
However, there is a report that (at least in some Systems), boot up processes
are slowed. This is associated with bootup testing of potentially needed modules.
Thus you may choose not to use this automation.
Support for the former driver pair, ltmodem + ltserial terminates with
2.6.15 kernels.
Lucent/Agere Mars/WinModem drivers from version 8.30 onwards have
the necessary fix for SMP machines which includes machines with
hyperthreading turned on (virtually acting as two CPUs).
Call waiting normally specified by, +pcw=1, is not implmented in the Linux drivers.
For older ISA card modems, specification of resources through forcing is
sometimes necessary: http://linmodems.technion.ac.il/archive-fifth/msg00055.html
The remainder of this section is historical info, awaiting a final edit.

Support packages for 2.6.n kernels are at:
http://phep2.technion.ac.il/linmodems/packages/ltmodem/kernel-2.6/ with folders for
debian/ containing some installers
ubuntu/ containing some installers
The ltmodem-8.26b1.tar.gz and ltmodem-8.31b1.tar.gz are driver compiling resources,
with the 8.31 having support for SMP (symmetric multi processor) motherboards.
These packages are more automated versions of the ltmodem-2.6-alk* packages
The ltmodem-2.6-Nalk.src.rpm packages can be used with rpm using Distros.
# rpmbuild --rebuild ltmodem-2.6-Nalk.src.rpm
will deposit an installer at:
/usr/src/rpm/RPMS/i686/ltmodem-kv_2.6.20-15-generic.rpm Check with
# ls -l /usr/src/rpm/RPMS/i686/ltmodem*
Then install with:
# rpm -i /usr/src/rpm/RPMS/i686/ltmodem-kv_2.6.20-15-generic.rpm
or similar.
The martian.tar.gz represents a new developmental track, meeting emerging kernel requirements.
See for details: http://martian.barrelsoutofbond.org/
http://linmodems.technion.ac.il/archive-sixth/msg00142.html
AMD x86_64 competency is provided only bt the martian.
For 2.4.n kernels packages are at http://ltmodem.heby.de/ or http://phep2.technion.ac.il/linmodems/packages/ltmodem/
There are some installer packages and also resources for compiling drivers.

SuSE/Novell Linux and some other Distros provide compiled drivers +installers.

ltmodem-8.26b1tar.gz 2.6.n without SMP support
* While SMP capacity should in principle be without ill effect on single processor systems,
the are some cases of ill effects on single processor systems.
