Hello,

I've recently installed Knoppix, a Debian-based Distro, to my HDD along with
Windows XP... only to find that my modem was actually a lucent-based
winmodem. After having compiled the latest kernel (2.6.10 at the time of
this writing) with gcc 3.3; I obtained, compiled and installed successfully
the latest drivers ltmodem-8.31a10.tar.gz. After configuring wvdial, I
obtain a "no dialtone" error message, here's my wvdial output:

===============================================

--> WvDial: Internet dialer version 1.54.0
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

--> Modem initialized.
--> Sending: ATDT195
--> Waiting for carrier.
ATDT195
NO DIALTONE
--> No dial tone.
--> Disconnecting at Fri Feb 18 18:31:41 2005

===============================================

I'm positive there is a dialtone since I can connect to the internet within
Windows XP on the same computer. I checked out the post-install problems
compilation from Jacques Goldberg, and applied all the "no dialtone"
solutions but none succeeded. The driver seems to be running, according to
lsmod :

=================================================

Judging from this, everything seemed fine; so I re-runned the scanmodem
script hoping I could get some extra information that didn't come out the
first time, before I had downloaded and installed the lucent driver. Here's
the output from scanmodem:

=================================================

I found curious the last line "lspci: -f: Invalid slot number"; I checked in
my BIOS settings to make sure PnP was disabled. I therefore decided to
include the lspci output too:

=================================================

I also tried to include the AT+GCI=xx (I replaced xx with various countries
running the same telephon system as mine, which is not listed) command to
set the country code but the modem wouldn't recognize this command so I
excluded it. Here's my wvdial.conf file:

=================================================

[Dialer Defaults]
Modem = /dev/ttyLT0
Baud = 115200
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem
Phone = 195
Username = abcdef
Password = 1234

=================================================

Of course, I replaced abcdef and 1234 respectively with my login and my
password. I also tried to connect with KDE's KPP Internet Dialer, it also
failed with the "no dialtone" error.

I hope I have provided enough informations to help locate the problem, thank
you very much for your support.
