Sorry Joshua for such a trivial answer, but this may happen, to me at least:
have you seen in the instructions (better, fresh, attached)
that you should create the following links (must be root to do it)
ln -s /dev/ttyAGS3 /dev/ttySAGR
ln -s /dev/ttyAGS3 /dev/modem
and of course rerun wvdialconf to see if wvdialconf will detect the modem.
Indeed, at least wvdialconf scans for modems at /dev/ttyS* which
The modem symbolic link is /dev/modem -> ttyAGS3
does not obey (note, always an S after tty ).

Hi,
I've recently purchased a Netcomm IN5920 pci modem (Agere chipset) to
replace an IN5699 which had worked well for years until last weekend
(it's gotten too noisy to make a connection).
I'd bought the 5920 off eBay naively assuming it would use the same
ltmodem driver (2.6-alk9) that worked on the 5699, but unfortunately
it doesn't. The ltmodem driver _seems_ to work partially - it responds
"OK" to an init string from pppd, but followed by "NO DIALTONE", and
if I try to use wvdial or minicom, the system freezes up.
So I've downloaded the latest scanModem (ModemData.txt attached) and
it suggests using the agrsm driver, which I've installed, but I can't
get it to work. The modem just doesn't respond to any command, whether
from pppd, minicom or wvdial.
Of course, it works fine in Windows 98, and I'm using it to send ths
email. Are there any other drivers I could try, or any other
suggestions?
This instruction set was provided by Hugo Canilli. He has thus had success with this AGRSM code requiring modem, under Linuxes: Ubuntu versions 6.10, 7.04, 7.10 and slackware 12.0. Marv Stodolsky lightly edited the text.
00) Be sure than kernel headers are installed. Under Ubuntu,
they are provided by a package pair with name format like
linux-headers-2.6.22-14 linux-headers-2.6.22-14-generic
with 2.6.22-14-generic being the boot kernel version
0) Download the package agrsm-20070804.tar.gz to your Desktop.
Open a terminal.
Type the following:
cd ~/Desktop
tar xzvf agrsm-20070804.tar.gz
cd agrsm
make
sudo make install
Note: the sudo is for usage in Ubuntu related Linux Distros/
For other Linuxes, first acquire Root/Adm powers with:
su - root
which will typically return a leading line with # ,
and Commands can be given without sudo:
make install
This completes the driver installation.
The two above steps need only be repeated when a new kernel is installed,
which always requires matching drivers.
1) Next load the drivers
sudo modprobe agrmodem
sudo modprobe agrserial
which should announce creation of /dev/ttyAGS3
2) It is convient to create symbolic links, which dialer utilities will follow,
to the real port /dev/ttyAGS3 .
sudo ln -s /dev/ttyAGS3 /dev/ttySAGR
sudo ln -s /dev/ttyAGS3 /dev/modem
Check with:
ls -l /dev/ttyAGS3 /dev/ttySAGR /dev/modem
whose output should include:
/dev/modem --> /dev/ttyAGS3
/dev/ttySAGR --> /dev/ttyAGS3
3) The first critical functial test is:
sudo wvdialconf /etc/wvdial.conf
which searches through potential ports for modem responses.
A success will end with a section like:
--------
ttySAGR<*1>: Modem Identifier: ATI -- Agere SoftModem Version 2.1.40
ttySAGR<*1>: Speed 4800: AT -- OK
ttySAGR<*1>: Speed 9600: AT -- OK
ttySAGR<*1>: Speed 19200: AT -- OK
ttySAGR<*1>: Speed 38400: AT -- OK
ttySAGR<*1>: Speed 57600: AT -- OK
ttySAGR<*1>: Speed 115200: AT -- OK
ttySAGR<*1>: Max speed is 115200; that should be safe.
ttySAGR<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 -- OK
Found a modem on /dev/ttySAGR.
Modem configuration written to /etc/wvdial.conf.
ttySAGR<Info>: Speed 115200; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
--------
Then you can proceed to try a dialout (see below).
A failure will include lines like:
ttyS0<*1>: ATQ0 V1 E1 -- failed with 2400 baud, next try: 9600 baud
ttyS0<*1>: ATQ0 V1 E1 -- failed with 9600 baud, next try: 115200 baud
ttyS0<*1>: ATQ0 V1 E1 -- and failed too at 115200, giving up.
Modem Port Scan<*1>: S1 S2 S3
Sorry, no modem was detected!
In this case there are a few Remedies to try.
R1) edit your grub or lilo parameter to the kernel with the option "pci=noacpi"
For example in a Ubuntu system, gedit can be used to modify the file /boot/grub/menu.lst
with command:
sudo gedit /boot/grub/menu.lst
The middle of menu.lst includes sections correponding to each bootup choice like:
title Ubuntu 7.10, kernel 2.6.22-14-generic
root (hd0,0)
kernel /boot/vmlinuz-2.6.22-14-generic ro quiet splash
initrd /boot/initrd.img-2.6.22-14-generic
quiet
Make a copy of this section, and edit to:
title Ubuntu 7.10, kernel 2.6.22-14-generic without acpi
root (hd0,0)
kernel /boot/vmlinuz-2.6.22-14-generic ro quiet splash pci=noacpi
initrd /boot/initrd.img-2.6.22-14-generic
quiet
Save the edit
Restart the computer.
Among the bootup options, make the new choice:
Ubuntu 7.10, kernel 2.6.22-14-generic without acpi
Test for modem detection, through steps 1,2 and 3
Go to the dialout test if successful.
R2) If not, try to disable the sound in the bootup BIOS.
R2a) Note a success can sometimes be achieved by moving the modem card to other PCI slot. But this option is not available on laptops.
See success report: http://linmodems.technion.ac.il/bigarch/archive-eighth/msg00304.html
Follow prior steps 1,2 and 3 for testing, retaining the bootup acpi=off parameter.
Dialout procedure
------------------
First edit in your dialout information with:
sudo gedit /etc/wvdial.conf
In the sample below, the lines beginning with are informative, not essential.
The line order is not important.
[Dialer defaults]
# Lines begining with # are comments.
# wvdial will look for this file at /etc/wvdial.conf
# or /home/LoginName/.wvdial.rc
Baud = 115200
Modem = /dev/ttySAGR3
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
# Lack of dialtone acquisition can be due to low line voltage,
# a common problem in Italy.
# Try inserting a "dial without waiting": X3
# Init2 = ATQ0 V1 E1 S0=0 X3 &C1 &D2 +FCLASS=0
# In case of connection instabilities, specify a lower frequency:
# Init2 = ATQ0 V1 E1 S0=0 X3 &C1 &D2 +MS=34
## Outside the USA, a country setting may be needed
# Init3 = AT+CGI=hexadecimal_country_code
ISDN = 0
Modem Type = Analog Modem
Phone = Dialout_phone_number
# if going through a switch board, a perhaps necessary pause can produced with a comma:
# Phone = 1,Dialout_phone_number
Username = LoginName
# if Internet Provider is MSN.net, use under Linux: MSN/LoginName
Password = YourPassWord
## If CONNECT is achieved but browsing fails, try activating the following line
# Auto DNS = yes
## To make a logfile wvdial.out
# wvdial 2>&1 | tee wvdial.out
# # For some Internet providers, the following line is necessary
# Stupid Mode = yes
## for other wvdial options, do "man wvdial" or see the documentation in
## /usr/share/doc/wvdial/
## End wvdial.conf
