Russel,

Marv sent the following message to list which should help you in
setting up your modem.  Read it carefully and apply the steps given.

First read http://linmodems.technion.ac.il/bigarch/archive-nineth/msg01316.html

More general info follows.
MarvS
============

Packages "agrsm" provide resources for compiling the agrmodem +
agrserial driver pair.

For the 11c11040 (VEN_11C1&DEV_1040) modem chips on High Definition
Audio cards, the driver resource
is called dkms-agrsm and maintained at
http://linux.zsolttech.com/linmodem/agrsm/ ,
There are a few installation formats. First install your Distro's dkms package
The dkms toolset automates compiling, including compiling of needed
update drivers
when an update kernel is installed.  Test if already installed with:
 dkms --help
If not installed or on your installation media, check your
distribution's repository.
See the example at
http://linmodems.technion.ac.il/bigarch/archive-eighth/msg03863.html
For Ubuntu, the repository is at http://packages.ubuntu.com. Comments
are more general compiling support are below.

http://linmodems.technion.ac.il/packages/ltmodem/11c11040/ has copies
and some updates
in Debian installation formats and related documentation and tools.
There is a agrsm_howto.txt, though it's leading compilation section is
not needed for all cases below.
There are a few cases of support implementation, depending on the host
system and particular chip type.
The agrsm-tools package creates symbolic links and runs a first functional test,
provided the wvdial package is installed.
Upon download and copying into your Linux partition, installation can
be done with:
       $ sudo dpkg -i agrsm*.deb
or one of the more sophisticated installation tools.

For a few Ubuntu kernels, driver installation packagea are at
  agrsm-2.6.27-7-generic_2.6.27-7.14_i386.deb
  agrsm-2.6.27-9-generic_2.6.27-9.14_i386.deb
for 2.6.27-7-generic and 2.6.27-9-generic kernels ONLY.
Resources are at http://linmodems.technion.ac.il/packages/ltmodem/11c11040/

For the modem chips 11c1:0620, 11c1:0630 and 11c1:048c(or f), the
current confirmed support is with the
agrsm-20090418.tar.gz  at
http://linmodems.technion.ac.il/packages/ltmodem/11c11040/
See Josh Crawford's report:
http://linmodems.technion.ac.il/bigarch/archive-eighth/msg00475.html.
The 11c1:0620 chipset is also supported by the dkms-agrsm package
(reports Hugo Canelli)

For implementation guidance, get the agrsm_howto.txt from
http://linmodems.technion.ac.il/packages/ltmodem/11c1040/ .
However the leading compiling section should be skipped for
installation done with dkms tools.
For Debian/Ubuntu related systems also get the from
http://linmodems.technion.ac.il/packages/ltmodem/11c11040/
the agrsm-tools_0.0.1_all.deb. Though lacking drivers, it automates
setup of symbolic links initiated by
       $  sudo modprobe agrserial
and also has a utility, called by:
       $  sudo  agrsm-test

For kernels earlier than 2.6.26 the more laborious procedures.
A simplest route is to get from
http://linmodems.technion.ac.il/packages/ltmodem/11c11040/ one of:
       kernel-2.6.21.0-22.i686.rpm
       linux-image-2.6.21.0-22_2.6.21.0-22_i386.deb
as their module set contains the drivers, but just for kernel 2.6.21.0-22.

For the Ubuntu 2.6.24-19-generic kernel, there is a driver package
agrsm-ubuntu8.04.1-2.6.24-19-generic.tar.gz

For kernels between 2.6.21 and 2.6.26 read the  HOWTO-Agere-11c11040-HDA.html,
which relates a laborious procedure involving kernel-source code.

A single root/adm command:
  modprobe agrserial
will provide for loading both drivers and symbolic /dev/ttySAGR link creation,
if the following two lines to some file in the /etc/modprobe folders.

install agrserial /sbin/modprobe --ignore-install agrmodem ;
/sbin/modprobe --ignore-install agrserial && \
test -e /dev/ttySAGR || ln -s /dev/ttyAGS3 /dev/ttySAGR
remove agrserial /sbin/modprobe -r --ignore-remove agrserial ;
/sbin/modprobe -r --ignore-remove agrmodem && { if test -L
/dev/ttySAGR; then rm /dev/ttySAGR; fi } ; true

They will alternatively be installed by the package agrsm-tools_0.0.1_all.deb
