sono nuova di ubunto (versione 9.10) installato su un notebook vergine 
(compac 615) e devo far funzionare il modem a 56k.
allora ho scaricato 
sia il  gnome-network-admin e scan modem. nel file Modemdata.txt scopro 
che il mio modem  :
pci slot           :  00:14.2
pci id              
:  1002:4383
subsystem id :  103c:308c
name             :  Audio 
device: ATI Technologies Inc SBx00 Azalia

e che  disabilitata! come 
posso abilitarla?
aggiungo tutto il file ModemData.txt

The PCI slot 00:14.2 of the modem card may be disabled early in 
 a 
bootup process,  but then enabled later. If modem drivers load 
 but 
the  modem is not responsive, read DOCs/Bootup.txt about possible 
fixes.
 Send dmesg.txt along with ModemData.txt to discuss a linmodems.

===== Advanced Linux Sound Architecture

The ALSA packages provide audio support and 
also drivers for some modems.
ALSA diagnostics are written during 
bootup to /proc/asound/ folders.

Support type needed or chipset:	agrsm


The 
AgereSystems/LSI agrsm code supports compiling of a agrmodem + agrsm 
driver pair.
One resource site is http://linmodems.technion.ac.
il/packages/ltmodem/11c11040/
Thereat get the agrsm_howto.txt and one 
of the agrsm-tools packages. 
The initial agrsm_howto.txt compiling 
steps are only cogent to modems with PCI IDs:
   11c1:0620, 11c1:048c 
and 11c1:048f chips. 
   They use the agrsm-20090418.tar.gz package.

The agrsm-tools sets a useful symbolic link and a agrsm-test utlity


For AgereSystems/LSI with Vendor 11c1 chips hosted on High Definition 
Audio cards, there may be support
through the agrsm resources 
(providing an agrmodem + agrserial driver pair) as an alternative to 
usage
of the snd-hda-intel driver + slmodemd helper. For the 11c11040 
modem chip, ONLY the agrsm code is competent.
Your Linux distro's dkms 
package should be first installed, as it directs the installation of 
modem 
specific dkms-agrsm resources, and also directs auto-
installation of new drivers upon kernel upgrades.

Currently, the dkms-
agrsm code is NOT competent for 2.26.28 and later kernels. 
A short 
term fix is to install linux-image + linux-headers packages for earlier 
kernels.
For detailed instructions for Ubuntu Jaunty with 2.6.28 
kernels, see http://linmodems.technion.ac.il/bigarch/archive-
nineth/msg01316.html

The primary dkms-agrsm resource site is http:
//linux.zsolttech.com/linmodem/agrsm/
whereat a few different packaging 
types are available. Debian type installers (supporting Ubuntu too)
are 
copied to http://linmodems.technion.ac.il/packages/ltmodem/11c11040/ . 
Thereat the current package
is the dkms-agrsm_2.1.80-6_i386.deb is for 
Agere/LSI chipsets hosted on High Definition Audio cards.  
Read the 
Modem/DOCs/Agrsm.txt for details.

 Completed candidate modem analyses.

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

 Versions 
adequately match for the compiler installed: 4.4.1
             and the 
compiler used in kernel assembly: 4.4.1


 
 Minimal compiling 
resources appear complete:
   make utility - /usr/bin/make
   Compiler 
version 4.4
   linuc_headers base folder /lib/modules/2.6.31-14-
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
