===== Advanced Linux Sound Architecture (ALSA) diagnostics =====
The ALSA packages provide audio support and also drivers for some modems.
ALSA diagnostics are written during bootup to /proc/asound/ folders.
The modem cards detected by "aplay -l" are: None
The /proc/asound/pcm file reports:
-----------------------

Vimicro Co.,ltd Lenovo USB2.0 UVC Camera at usb-0000:00:1d.7-8, high speed
PCI slot 00:1b.0 has a High Definition Audio Card
The drivers are in the kernel modules tree at:
/lib/modules/3.8.0-19-generic/kernel/sound/pci/hda/snd-hda-intel.ko
The HDA diagnostics did not recognize a modem chip on the audio subsystem,
though a Conexant chip modem might not be recognized.
=== Finished firmware and bootup diagnostics, next deducing cogent software. ===
A candidate modem is not transparent among the PCI devices:

------------------------------------------------
with USB, bridge, and RAM devices not displayed.
If a High Definition Audio card is present, if might be hosted on the Subsystem.
If your modem is an
external USB type,
connected by an external serial cable,
or mounted internally on an ISA card,
then scanModem would not access it.
Try with Root permission
$ sudo wvdialconf /etc/wvdial.conf
to detect these modem types and some USB modems.
If the detection is successful, read the DOCs/wvdial.txt .
Edit the /etc/wvdial.conf with Root permission:
sudo gedit /etc/wvdial.conf
will be able to dial out with Root permission:
sudo wvdial
Many modems for which scanModem fails have Conexant chips.
From http://www.linuxant.com/drivers/modemident.php
get the ListModem tool, which will report on Conexant chipset modems
If the above tests fail, please provide any independent information available on your modem.
If an alternative boot into Microsoft windows can be done, do mouse
clicks on:
Start > Settings > Control Panel > Classical View (for Window XP) > System
> Hardware > Device Manager > Modems > Click on the + > Modem. Double click to
expand the graphic. Manufacturer information may be displayed. For example, CXT
stands for Conexant. Click the Diagnostics Tab. Record any hardware ID or vendor
and device information. From the Driver Details TAB, copy out the VENdor and DEVice information.
Next do the Query Modem and record the ATI specifications displayed such as:
ATI3 - Agere SoftModem Version 2.1.22
ATI5 - 2.1.22, AMR Intel MB, AC97 ID:SIL REV:0x27
Try to identify the modem setup file, with name perhaps MODEM.INF.
If may contain chipset Vendor informaton.

Support type needed or chipset:
Support can likely be achieved through two mutually exclusive alternatives:
1) The hsfmodem software for Conexant chipset modems: Read DOCs/Conexant.txt
The following ALSA alternative CANNOT work with Conexant modems.
2) An ALSA modem driver plus slmodemd. Read DOCs/Smartlink.txt for details, and
to test get the package SLMODEMD_gcc4.7_alsak3.8.0.tar.gz from:
http://linmodems.technion.ac.il/packages/smartlink/
The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.7.3
and the compiler used in kernel assembly: 4.7
linux-headers-3.8.0-19-generic resources needed for compiling are not manifestly ready!
If compiling is necessary packages must be installed, providing:
linux-headers-3.8.0-19-generic
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

In case of an "error 17" "serial loopback" problem, see:

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

For guidance on FAX usage, get from http://linmodems.technion.ac.il/packages/ get faxing.tar.gz
It has samples for a modem using port /dev/ttySL0, which must be changed to match your modem's port.
Read Modem/DOCs/YourSystem.txt concerning other COMM channels: eth0 wlan0
Which can interfere with Browser naviagation.
Don't worry about the following, it is for experts should trouble shooting be necessary.
