Re: Out of 3 modems... only one works (and badly)!

Well, I wasted so much time on that issue that I will not swear that I am right, but as far as I could find, forcing /dev/modem to /dev/ttySHF1
will not help because hsfconfig insists using /dev/ttySHF0.
Even disabling or even removing the starter file in init.d is not enough.
Removing the modules neither: hsfconfig recompiles them immediately.
Whence I just rpm -e until I need rpm -i again.

Alessandro,

Jonathan can best answer you questions below, on hsfmodem issues.

But the /dev/modem issue is related to the fact that /dev/ space is
dynamic, created new upon each bootup upon  /dev/.udev/ in response to
the actual hardware present and rules in /etc/udev/ .  LIkely you can
change a spec in /etc/udev/ to fix
  /dev/modem -> /dev/ttySHSF1
   This scheme of creating device nodes only as needed GREATLY
dinimishes the amount of disk & RAM which must be devoted to device
control issues, as contrasted to the original scheme of having all
possibly needed node specs written in /dev/

Marvin,

Thank you so much... I just didn't realize that having ALSA finally
working after my last installation also has allowed the HDA modem control.
I switched the modem symb.link to ttySHSF1 and, as for now, it works fine.
Just a couple of details:
1. I rm-ed the old modem link to ttySHSF0 ($ rm /dev/modem) and ln-ed a
new one to ttySHSF1 ($ ln /dev/ttySHSF1 /dev/modem), but, after restart,
it was restored to ttyHSFS0. How to change it permanently? (sorry if
this is not the right place to ask)
2. Can I also permanently switch the Linuxant license from one modem to
the other by re-recording, or am I supposed to start another one?

Thank you again!

Alessandro,
   Support by Linuxant for their software is good.
Run the
# hsfconfig --diagnose
whose log file is written to /tmp
and send it to "Support (Jonathan)" <support@xxxxxxxxxxxx>

One issue may be the ALSA version.
The hsfmodem drivers do rely on the ALSA snd-hda-intel.  If there is a
version mismatch, that could contribute to problems.

TO show the dependencies, run
# lsmod | grep hsf

Hi All,

I am here posting my ModemData.txt output, after running scanModem. My
fairly odd situation is that I had to make experiment with 3 (sic)
different modems on my Asus laptop to get some some results (i.e. to
access internet via Linux):
1. the integrated modem of the HDA soundcard (no way)
2. a PCMCIA card modem (no way)
3. an external USB modem by Trust (which works, but...)

The thing is (apart from the not-so-smart final solution), the USB modem
is able to be mounted as /ttySHSF0 and connect, but, after a random time
on-line, the system crashes, getting "frozen" all of a sudden. So, what
I would like to please ask you all to give some help is:
    i. have you ever been aware of such problems with external USB
modems? Please note I have suffered from the same problem with various
kernel versions (and distros), always updated with their respectively
appropriate HSF drivers.
    ii. in case, has anybody any idea how one of the other two modems
should be set up so as to work? Actually, this should prevent me from
the other problem, and I obviously would like to have the more
integrated modems work...

Thank you in advance. This is my ModemData.txt output (please note the
USB2.0 device is the webcam...) :

 Completed candidate modem analyses.

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

 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/2.6.18.8.tex5/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
