Installers are available at:

as RPM packages containing binary images of drivers
applicable for installation on the following systems:

* RedHat 8.0 (kernel version 2.4.18-14, sm56-06.05.00-1.rh8.i386.rpm)

There is also available a Legacy driver - SM56_5.1_I386.rpm for 2.4.n
kernels ONLY
for which the advice at http://www.sm56.tk/ may be effective.
Jan Ibanez <jmibanez@gmail.com> is our expert on Motorola problems
Achieving function with these drivers is often difficult.
If you computer alternatively boots Linux and Microsoft OS,
do a complete PowerOff before starting Linux.
Otherwise there may be an error during following Motorola usage:
SM_DisplayFatalErr
Some guidance for particular cases is:

There is a volunteer Motorola site: http://www.sm56.tk/
The installation creates a driver sm56.o , the character devices
/dev/motomem
/dev/sm56
with symbolic link /dev/modem --> /dev/sm56
the /etc/modules.conf lines:
alias char-major-24 sm56
options sm56 country=1
and documentation in usr/share/doc/HTML/en/sm56/ and "man sm56"
An additional line in /etc/modules.conf
alias /dev/modem /dev/sm56
would beneficially aid driver autoloading, without which there may be a
failure of the wvdial functionality test:

Vendors 127a and 14f1 are Conexant, successor to Vendor=148d Rockwell
technology.
With respect to software support there are two main types, hcfmodem* and
hsfmodem* .
http://linmodems.technion.ac.il/resources.html#conexant has scripts
For HSF modems.
For HCF modems.
aiding installation.
The HCF (Host Controller Free) which have a digital signal processsing
(DSP) chipset,
while the HSF in the soft modem family without a dsp.
HSF support of version 5.03 is included with SuSE 9.0 for support of
2.4.21 version kernels.
For support of 2.6.n kernels, new releaseses are provided at
http://www.Linuxant.com/drivers/
Linuxant is providing free test packages for low speed CONNECTs.
There is a one time subscription fee for full high speed support.
A detailed software installation example is provided at:

Modems with the following PCI_IDs also have Conexant HCF (Controller free)
chipsets.
1024:1024 (Zenith Data Systems)
148D:1003 (DIGICOM Systems)
158B:0015 (Allied Data Technologies Tornado VFM56x-PRC)
141A:1035 (Apache Micro)
The following six may be either HCF of HSF modems. Test the HSF package
first
(127a,14f1):(1025,1085, 2005)
Should a HCF driver installation fail to serve among there,
then uninstall and instead try the HSF driver resource.
Subsystem HSF Conexant soft modems serve under AC97 or MC97 controllers.
These include:
14f1:(5422 2002) , plus many others with vendors assigned PCI IDs.
SubSystem 104d:814e under a 1039:7013 Silicon Integrated Systems modem
controlled has a Conexant chip
After loading of HSF drivers, there will be displayed by
command: /sbin/lsmod
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 a conflict between modules snd-intel8x0m and hsfmc97ich.
The snd-intel8x0m Must be loaded first or the system may hang upon
hsfmc97ich insertion.
