Bob,
Why this string:
ATM1L3DT6875000 ?
The whole thing is incoherent.
At this time I tend to believe that:
Ubuntu blindly installs a link /dev/ttySL0 to /dev/modem without
checking that the kernel module serving modems matching ttySL0 are
indeed loaded in the computer.
This link will fool wvdialconf if no modem kernel module (=driver) is
loaded.
When no driver is running, the dial command is sent into vacuum, etc...,
exactly as you report.
Furthermore, who introduced the string ATM1L3DT6875000 ?
You? Some hidden program?
It is NOT there in /etc/wvdial.conf !
Let us begin from the beginning.
Would you please download
http://linmodems.technion.ac.il/packages/scanModem.gz
then decompress scanModem.gz with command
gunzip scanModem
then make it executable with
chmod a+x scanModem
then execute it with
sudo scanModem
This will create a directory Modem
In that directory, find the file ModemData.txt (not all the rest) and
send it to us.
ttySL0 suits SmartLink and most but not all AC'97 modems.
Inspecting ModemData.txt we will tell you which driver should be loaded.
So let us add here the next step. Type sudo lsmod > lsmod.txt
and add this file to your reply which will thus contain ModemData.txt
and lsmod.txt
The next step will be:
rm /dev/modem
to unlink /dev/ttySL0
Then sudo wvdialconf /etc/wvdial.conf
and send /etc/wvdial.conf without any editing (do not waste time with
number, name, password).
Three files to be sent, please.

Greetings,
I am a Linux and Ubuntu newbie attempting to donate
40+ surplus computers to disadvantaged students and
their families at our school here in West Texas. I am
setting them up with Edubuntu 7.04 because of the Open
Office and educational software. These families cannot
afford cable or DSL connections (these computers all
have working eth0 connections) so I am attempting to
install modems for (possibly affordable) Internet
access.
wvdial has been installed and dials out, however when
it connects and I am supposed to get a TTY display (or
something) to type into, I never get one.
It shows the disconnect message, but fails to hangup,
leaving the line and carrier active until the provider
times out. This continues until reboot.
After the disconnect message below, the modem
/dev/ttySL0 disappears and cannot be found. The
computer must be rebooted, after which everything
works again up to the point shown.
ALSO: I cannot figure out how to get a full set of
debug messages turned on or saved from wvdial and
other utilities like pppd and gnome-ppp.
Below are the texts from Gnome-ppp dialout, wvdialconf
output, wvdial.txt, and /etc/wvdial.conf.
Thanks for all you do!
