Some modem drivers can only be used in 32 bit modem on x86_64 systems,
while some others are competent on x86_64 Systems.  Cases are:
1) http://linmodems.technion.ac.il/bigarch/archive-seventh/msg03119.html for the snd-hda-intel audio+modem driver. Also applicable to AC97 modem controllers.
In both cases, 32 bit libraries must be installed to support the slmodemd helper having a precompiled 32 bit component.
2) For USB modems using the slusb.ko driver. 32 bit libraries must be installed to support the slmodemd helper having a precompiled 32 bit component
3) The hsfmodem and hcfpcimodem drivers for Conexant chipsest modes are x86_64 competent.

There are no blacklisted modem drivers in /etc/modprobe* files Attached USB devices are: ID 04e8:1623 Samsung Electronics Co., Ltd ID 03f0:2b17 Hewlett-Packard ID 046d:c018 Logitech, Inc.

provide audio + modem support with the modem chip residing on the subsystem.
Any particular card can host any one of several soft modem chips.

Writing DOCs/Intel.txt

Vendor 11c1 is Lucent Technologies with modem technology now under LSI Inc. Their Linux code developer/maintainer is Soumyendu Sarkar. Support for a chipset and its continued maintenance is only initiated at the request of a major chipset buyer, or comparable sponsor. Several different modem chipset types are produced: with varying support under Linux.

 Compiling resources for a driver module pair: agrmodem.ko + agrserial.ko
 Use the  agrsm-HDA-20080721-ALSA15.tar.bz2 or agrsm-HDA-20080721.tar.bz2
 Read the agrsm_howto.txt.  For 11c11040 chips, also the HOWTO-Agere-11c11040-HDA.html


The AGRSM code package is not yet functionally on x86_64 systems, except in Intel architecture
emulation mode. This is because there is a 32 bit encypted component, precompiled at LSI/Agere Inc. It cannot be functionally linked with other 64 bit components compiled on a x86_64 system. When/if LSI Inc. provides the encypted component in 64 bit format, service will be possible.

Completed candidate modem analyses.

The base of the UDEV device file system is: /dev/.udev

Versions adequately match for the compiler installed: 4.2.3
            and the compiler used in kernel assembly: 4.2.3



Minimal compiling resources appear complete:
  make utility - /usr/bin/make
  Compiler version 4.2
  linuc_headers base folder /lib/modules/2.6.24-16-generic/build

However some compilations and executable functions may need additional files,
in the FileNames.h (so called kernel "h"eaders) collection installed in  /usr/include/ .
For martian_modem, additional required packages are needed. The also required headers of package libc6 are commonly installed by default. Compiling hsfmodem drivers does require linux-libc-dev and libc6-dev packages, for kernels 2.6.24 and later versions.
In not included on your install CD, search for them at http://packages.ubuntu.com
or comparable Repository for other Linux distros.
When compiling ALSA drivers, the utility "patch" will also be needed.




If a driver compilation fails, with message including some lack of some FileName.h (stdio.h for example), then
Some additional kernel-header files need installation to /usr/include. The minimal additional packages are libc6-dev
and any of its dependents, under Ubuntu linux-libc-dev

If an alternate ethernet connection is available,
$  apt-get update
$  apt-get -s install linux-kernel-devel
will install needed packages.
For Debian/Ubuntu related distributions, run the following command to display the needed package list:

Otherwise packages have to be found through http://packages.ubuntu.com
Once downloaded and transferred into a Linux partition,
they can be installed alltogether with:
$ sudo dpkg -i *.deb


Checking pppd properties:
	-rwsr-xr-- 1 root dip 313600 2007-10-04 22:48 /usr/sbin/pppd

In case of an "error 17" "serial loopback" problem, see:
   http://linmodems.technion.ac.il/linmodems/archive-sixth/msg02637.html

To enable dialout without Root permission do:
	$ su - root  (not for Ubuntu)
       sudo chmod a+x /usr/sbin/pppd
or under Ubuntu related Linuxes
	sudo chmod a+x /usr/sbin/pppd

Checking settings of:	/etc/ppp/options
asyncmap 0
noauth
crtscts
lock

modem
proxyarp
lcp-echo-interval 30
lcp-echo-failure 4
noipx

In case of a message like:
  Warning: Could not modify /etc/ppp/pap-secrets: Permission denied
see http://linmodems.technion.ac.il/bigarch/archive-sixth/msg04656.html

Read Modem/DOCs/YourSystem.txt concerning other COMM channels: eth0
Which can interfere with Browser naviagation.

Don't worry about the following, it is for experts should trouble shooting be necessary.
