Hi list, I'm trying to install a modem with the Smartlink SL2801 chip
in Ubuntu Gutsy and I need some help. Is it supported or I'm wasting
time trying?
lspci reports it as:
00:0b.0 Modem: PCTel Inc HSP MicroModem 56 (rev 02) (prog-if 00 [Generic])
Subsystem: PCTel Inc PCT789 adapter
Flags: medium devsel, IRQ 16
I/O ports at e400 [size=64]
Capabilities: [40] Power Management version 2
I tried running the setup script from pctel-0.9.7-9-rht-8. It compiled
and installed everything fine, linmodem, pctel and pctel_hw modules
are loaded when system starts, the /dev/modem link is correct, and I
don't know if it was this script that made it, but now "PCTEL hardware
modem driver: binary part of driver" appears in the restricted
controllers tool of Ubuntu, as Enabled and in use.
But I get no response from the modem. Tried to run the test with
wvdial, and made the modem queries with kppp with no result. Except
when I run the script for the first time and it install the drivers.
At that moment, if I run the ATI Queries with kppp, they are all made,
but the results are all empty.
Also, here is a snippet from dmesg:
[ 47.209606] linmodem(1265): linmodem v0.1 loaded

[ 47.314477] ttyS_PCTEL0 at I/O 0xe400 (irq = 16) is a PCTel
Something that worried me was that line that says that the device is
grabed by driver serial, but there is no module serial loaded, and I
disabled all serial ports from the bios, but this message is still
there.
So i tried with ungrab-winmodem, after unloading the modem modules and
loading ungrab-winmodem, loading modem modules didn't show that
message, but still there was no answer from the modem, I was again in
the case where empty values were returned from the ATI queries.
I attach the ModemData.txt output of scanModem for more details.
Thank you very much,
Merry Christmas and Happy New year to everybody
Santiago.

There are no blacklisted modem drivers in /etc/modprobe* files
Potentially useful modem drivers now loaded are:
linmodem
The Advanced Linux Sound Architecture (ALSA) packages providing audio support on your System,
also includes drivers for some modems. High Definition Audio (HDA) cards can themselves host
a softmodem chipset, with both audio+modem supported by a snd-hda-intel driver.
The ALSA diagnostics are written during bootup to /proc/asound/ folders.
Modem not detected though HDA card diagnostics, though not excluding
a possible Conexant modem chip impervious to ALSA diagnostics.
Proceeding through alternative possibilties.
Summary card and chipset information is in:

The PCI slot 00:0b.0 of the modem card may be disabled early in
a 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 discuss@xxxxxxxxxxxxx

Writing Pctel.txt
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.
Compressed files at: /usr/src/linux-source-2.6.22.tar.bz2
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 pacakage
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

To enable dialout without Root permission do:
$ su - root (not for Ubuntu)
sudo chmod a+x /usr/sbin/pppd
