scanModem update of: 2008_01_22
There are no blacklisted modem drivers in /etc/modprobe* files
The Advanced Linux Sound Architecture (ALSA) packages providing
audio
support,
also includes drivers for some modems. The ALSA diagnostics are
written
during
bootup to /proc/asound/ folders.
The /proc/asound/ audio+modem diagostics are being copied.
Finished copy to Modem/ALSAdanilo.tgz
The ALSA verion is 1.0.14
The modem cards detected by "aplay -l" are:
tarjeta 1: modem [VIA 82XX modem], dispositivo 0: VIA 82XX modem

Lacking a dsp (digital signal processing) chip, the modem is a
software
intensive or "softmodem" type. Its primary controller manages
the traffic
with the CPU. But the software needed is specified in the
Subsystem.
-----------------------------------------
Support type needed or chipset: slmodemd
An ALSA (Advanced Linux Sound Architecture) modem driver:
snd-via82xx-modem
provides Low Level support enabling contact with the modem
hardware.
For all BUT Conexant chip soft modems (using hsfmodem software)
complementary High Level support is through a Smartlink
utility: slmodemd
Download from
http://linmodems.technion.ac.il/packages/smartlink/
the package SLMODEMD.gcc4.1.tar.gz having a compiled slmodemd.
Unpack
under Linux with:
$ tar zxf SLMODEMD.gcc4.1.tar.gz
and read instructions therein. But briefly, the modem is setup
with
command:
sudo slmodemd -c YOUR_COUNTRY --alsa modem:1
reporting dynamic creation of ports:
/dev/ttySL0 --> /dev/pts/N , with N some number
Read Smartlink.txt and Modem/YourSystem.txt for follow through
guidance.

Writing Smartlink.txt
============ end Smartlink section =====================
Completed candidate modem analyses.
The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.1.3
and the compiler used in kernel assembly: 4.1.3
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.1
linuc_headers base folder
/lib/modules/2.6.22-14-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 libc6-dev
(and for
Debian/Ubuntu, linux-libc-dev). The also required headers of
package
libc6 are commonly installed by default.
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 package
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 269256 2007-10-04 14:57 /usr/sbin/pppd
In case of an "error 17" "serial loopback" problem, see:
http://phep2.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
hide-password
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/YourSystem.txt concerning other COMM channels: eth0
Which can interfere with Browser naviagation.
Don't worry about the following, it is for the experts
should trouble shooting be necessary.
