 Here is the output from ScanModem:

Please especially look at <----- points . I added comments / questions after <----------- ? .

Much more info at https://bugs.launchpad.net/ubuntu/+bug/1087519 .

-------------------------- System information ----------------------------
CPU=x86_64, Ubuntu , ALSA_version=1.0.24
Linux version 3.2.0-38-generic (buildd@allspice) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #59-Ubuntu SMP Tue Feb 5 17:53:03 UTC 2013
 scanModem update of: 2011_08_08

Distrib_ID=Ubuntu
DistribCodeName=precise
AptRepositoryStem=http://us.archive.ubuntu.com/ubuntu/

The dkms driver upgrade utilities are installed,

Some modem drivers can only be used in 32 bit modem on x86_64 systems, <-------- ? this is a 64 bit system, but not linmodem
while some others are competent on x86_64 Systems. Cases are:
1) http://linmodems.technion.ac.il/bigarch/archive-seventh/msg03119.html
for the snd-hda-intel audio+modem driver. Also applicable to AC97 modem controllers.
In both cases, 32 bit libraries must be installed to support the slmodemd helper having a precompiled 32 bit component.
2) For USB modems using the slusb.ko driver. 32 bit libraries must be installed to support the slmodemd helper having a precompiled 32 bit component
3) The hsfmodem and hcfpcimodem drivers for Conexant chipsest modes are x86_64 competent.
4) agrsm packages for LSI/AgereSystems softmodems are not competent on x86_64 systems.

 There are no blacklisted modem drivers in /etc/modprobe* files

 Potentially useful modem drivers now loaded are:
 snd_hda_intel <------------------ ?

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

 Versions adequately match for the compiler installed: 4.6.3
 and the compiler used in kernel assembly: 4.6

 linux-headers-3.2.0-38-generic resources needed for compiling are not manifestly ready! <------------------ ?!?

 If compiling is necessary packages must be installed, providing: <------------------ ?!?
 linux-headers-3.2.0-38-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

Checking pppd properties:
 -rwsr-sr-- 1 root dip 325744 Feb 4 2011 /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
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

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
Which can interfere with Browser naviagation.

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

 Checking for modem support lines:
 --------------------------------------

slmodemd created symbolic link /dev/ttySL0: <------------------ ? not ttyS4 ?
 Within /etc/udev/ files:

 Within /etc/modprobe.conf files:

/etc/modprobe.d/blacklist-modem.conf:# blacklist snd-atiixp-modem
/etc/modprobe.d/blacklist-modem.conf:# blacklist snd-via82xx-modem
 Within any ancient /etc/devfs files: Within ancient kernel 2.4.n /etc/module.conf files:
 
 
The reasonable man adapts himself to the world.
The unreasonable man persists in trying to adapt the world to himself.
Therefore, all progress depends on the unreasonable man.
