Hello,
I've been bashing my head against this problem for over a week now, so any
help will be gratefully received.
My modem is a SmartLink USB56 2.0
My problem is that I have instlalled slmodem_2.9.11 on my clean Fedora
Core 6 installation (2.6.18-1.2798.fc6), followed the instructions to
unpack, compile, install and insert the appropriate kernel modules, and
have the modem up and running on /dev/ttySL0 (linked to /dev/modem). I
can reach the modem fine using minicom/wvdial/kppp etc., and after
tweaking the AT commands based on the numerous suggestions on the web, can
hear the modem dialing a number.
However, I repeatedly get the No Carrier message, which other people seem
to frequently encounter. I've tried various settings in wvdial.conf and
directly in minicom, but all without success.
Any light you can shed on this will be very gratefully accepted!
Mick

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.

The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.1.1
and the compiler used in kernel assembly: 4.1.1
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.1
linuc_headers base folder /lib/modules/2.6.18-1.2798.fc6/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

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)
chmod a+x /usr/sbin/pppd
or under Ubuntu related Linuxes
chmod a+x /usr/sbin/pppd
Checking settings of: /etc/ppp/options
lock
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.
