Linux version 2.6.22-14-generic (buildd@terranova) (gcc version 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)) #1 SMP Fri Feb 1 04:59:50 UTC 2008
 scanModem update of:  2008_03_04


 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 ALSA verion is 1.0.14
The modem cards detected by "aplay -l"  are:
card 1: Modem [SiS SI7013 Modem], device 0: Intel ICH - Modem [SiS SI7013 Modem - Modem]

The /proc/asound/pcm file reports:
-----------------------
00-01: Intel ICH - MIC ADC : SiS SI7012 - MIC ADC : capture 1
00-00: Intel ICH : SiS SI7012 : playback 1 : capture 1
01-00: Intel ICH - Modem : SiS SI7013 Modem - Modem : playback 1 : capture 1

about /proc/asound/cards:
------------------------

                      SiS SI7012 with ALC655 at irq 16
 1 [Modem          ]: ICH-MODEM - SiS SI7013 Modem
                      SiS SI7013 Modem at irq 16


The driver snd-intel8x0m with its dependent drivers:

 The PCI slot 00:02.6 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 Bootup.txt about possible fixes.
 Send dmesg.txt along with ModemData.txt to discuss@xxxxxxxxxxxxx
 if help is needed.

 This is a NEW softmodem case!  Please send the output ModemData.txt 
 to DISCUSS@xxxxxxxxxxxxx to enrich the Archive and help others!

     New Case Only
 -------------------------------------------
 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-intel8x0m
 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://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
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.
