 scanModem update of:  2007_Sept_07


 There are no blacklisted modem drivers in /etc/modprobe*  files 
USB modem not detected by lsusb


Several modems are supported by drivers with ALSA, the Advanced Linux Sound Architecture software.
Copying ALSA diagnostics to Modem/ALSAroot.tgz
ALSAversion = 1.0.13

Modem or candidate host audio card have firmware information and diagnostics:

 This is a NEW softmodem case!  Please send the output ModemData.txt 
 to DISCUSS@xxxxxxxxxxxxx , even if further assistance is not needed.
 It will enrich the Archive and help others!
 -------------------------------------------
 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.

 Already loaded into the kernel is snd-via82xx-modem and audio drivers it depends on,
 displayed by:	lsmod | grep snd_via82xx_modem

The diagnostic outputs for this softmodem section have their raw information in
folders and text files under /proc/asound/ which you can browse. The information
is from files:
	/proc/asound/pcm
-------------------------------
01-00: VIA 82XX modem : VIA 82XX modem : playback 1 : capture 1
00-01: VIA 8235 : VIA 8235 : playback 1 : capture 1
00-00: VIA 8235 : VIA 8235 : playback 4 : capture 1

	/proc/asound/modules
-------------------------------

 1 snd_via82xx_modem
	/proc/asound/card1/codec97#0/mc97#1-1+regs
-------------------------------
0:7c = 5349  and  0:7e = 4c21
which were translated from hexadecimal code into:  SIL21

	/proc/asound/card1/codec97#0/mc97#1-1

Extended modem ID: codec=1 LIN1

and from the command:
	aplay -l | grep -i modem

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: 4.1.2
             and the compiler used in kernel assembly: 4.1.2


 
 Minimal compiling resources appear complete:
   make utility - /usr/bin/make
   Compiler version 4.1
   linuc_headers base folder /lib/modules/2.6.20-16-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 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 files with message including some lack of some FileName.h (stdio.h for example. 
Some additional kernel-header files need installation to /usr/include.
For Debian/Ubuntu related distributions, run the following command to display the needed package list:
$ sudo apt-get -s install linux-kernel-devel
While some of the files may be on the install CD, others may have to be found through http://packages.ubuntu.com

For Ubuntu Feisty, additional packages required were:
 libc6-dev linux-libc-dev
available through http://packages.ubuntu.com/ , if not on the install CD.
Such packages may have different names for other Linux distributions.
Try installing just the libc6-dev, then test the compile again.


Checking pppd properties:
	-rwsr-xr-- 1 root dip 269224 2007-04-04 23:41 /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 eth1 eth1:avah
Which can interfere with Browser naviagation.

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