I am trying to get a ltmodem driver going for my computer. The machine
is an older P400 IBM Aptiva that came with an internal v90/fax/voice
modem. Now that the machine has Fedora Core 3 installed the modem is
identified as an "unknown device" with the name "LT Win Modem". The
pnpdump tool identifies it as "GVC5719/1710593[0] {LT Win Modem}".
Looking at the hardware it is an ISA card with a big black plastic
shroud over most of the card. The scanModem output is at the bottom of
the note.
Being unable to find a pre-built RPM for FC3 I thought I'd have a go at
building the source. So far I have tried two versions with mixed unsuccess.
http://alk.at.tut.by/ltmodem-2.6-alk-4.tar.bz2
and
http://linmodems.technion.ac.il/packages/ltmodem/kernel-2.6/ltmodem-2.6-7alk.src.rpm
I have followed the instructions diligently to the best of my ability
and for both the result is the same. That is, when I try to do
insmod ltmodem
it works fine, but
isnmod ltserial
gives me the message
insmod: error inserting 'ltserial.ko': -1 No such device
Any ideas what I can do to track down why ltserial is objecting?
Kind regards,
Mike

The kernel-2.6.11-1.35_FC3 was compiled with CONFIG_REGPARM, providing
more compact and faster code.
The kernel was assembled with compiler: 3.4.3
with current System compiler GCC=3.4.3
Checking for kernel-headers needed for compiling.
The kernel-headers have base folder:
/lib/modules/2.6.11-1.35_FC3/build
Please install the package WVDIAL for modem testing and dialout.
Modem symbolic link is: /dev/modem -> /dev/ttyLT0
USB modem not detected.

A modem was not detected among the above PCI devices.
This indicates that the modem, if present has a non-standard or ISA
bridge.
Please follow the directions in Modem/SoftModem.txt for identifying
the modem properties
when booting under Microsoft Windows. Also access any documentation
sources
on yourchipset. Guidance can only be provided AFTER
the chipset and/or its drivers have been identified.
The IBM mwave modem does have a driver within 2.6.n kernel+module
releases. If is at:
/lib/modules//kernel/drivers/char/mwave/mwave.ko
and can be loaded only if Mwave hardware is present Test with:
# su - root
followed by
# modprobe wmave
If successful see:
http://tedfelix.com/Mwave/
http://www.linuxdocs.org/HOWTOs/mini/ACP-Modem/ , section 2.4 and
later.

A failure response has output like:

Beginning with Fedora 2 kernel-2.6.6-1.427, kernel-headers needed
for compiling drivers are provide at: /lib/modules/kernel-version/build/
Thus upgrading above kernel 2.6.5-1.358 to 2.6.6-* is Stongly Recommended
pppd version 2.4.2 may not be fully compatible with 2.6.8 kernel
releases.
If an initial CONNECT is achieved without PPP being subsequently
established,
drop back to a 2.4.1 version. This has worked for PCTEL AMR modem users,
supported by the http://www.smlink.com slmodem software.
Check pppd version with:
pppd --version
See http://linmodems.technion.ac.il/archive-fourth/msg03167.html
For kernel-version 2.4.20-8 , a failure in automatic loading of PPP
related modules
has been reported. It was necessary to manually load with:
/sbin/modprobe /lib/modules/2.4.20-8/kernel/drivers/net ppp_generic
/sbin/modprobe /lib/modules/2.4.20-8/kernel/drivers/net ppp_deflate
/sbin/modprobe /lib/modules/2.4.20-8/kernel/drivers/net ppp_synctty
/sbin/modprobe /lib/modules/2.4.20-8/kernel/drivers/net ppp_async
or dialout efforts failed.
The Internet Configuration Wizard writes a configuration file:
/etc/wvdial.conf
containing a line default line
Stupid Mode = yes
Better dialup performance may be achieved by commenting out this line as:
# Stupid Mode = yes
Also non-USA Users may need to add to the [Modem0] block:
Init2 = AT+GCI=hexadecimal_country_code
but test without it first.
redhat is not yet providing pre-compiled drivers for WinModems
