Hi all. "Of course" I had troubles in getting my modem working on
my office laptop.... I used GNOMEPPP, but to no avail, getting
most of the times a "unavailable carrier" error or a tim out.
Here follow some "boundary conditions": LAPTOP: hp compaq nc6000
O.S.: WinXP on the laptop built-in HDD; Ubuntu 7.10 (Gutsy
Gibbon) booting from external USB HDD KERNEL: Linux
2.6.22-14-generic WM: GNOME 2.20.1
Here follows the result of running scanModem as reported into the
ModemData.txt output file (which you can also fin attached):

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

------------------------------------------- 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.

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

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

I would really appreciate any help as to: - type / model / built
of modem chipset - supporting status - troubleshooting to be
acted upon.
Many thanks in advance. Best regards. Giancarlo
