Winmodems

How does one get JDS to recognize the internal modem?
YAST2 does not see it. I have a Toshiba Tecra.
Try to configure it from "launch/system/hardware/modem".

I should point out that most internal modems are software modems (also known as winmodems), the only way to get these working is by finding the correct drivers, which is usually quite rare but not impossible), the first website to look at would be:

http://www.linmodems.org

or

http://www.linux-laptop.net/

Download the file
slmdm-2.7.10.tar.gz
Some of the newer version cause the modem to dial incorrect number.

To compile this you need to install kernel-source first and also some development packages. The easiest is using yast2
Launch->Application->System Tools->Install/Remove Software

In Development Tools Selection tick the kernel-source then automatically all the other required packages for compilation will be selected also (binutils, make, gcc etc). After that click Accept and insert the CD as asked by the dialog windows.

unzip the packages you have downloaded above

$ tar zxvf slmdm-2.7.10.tar.gz

Go to the directory slmdm-2.7.10 and edit the Makefile using vi
Remove the lines and paragraph related to usb because it will cause error if you try to compile in JDS

after that just type

make

make install-amr

your /dev/modem should be linked to /dev/ttySL0 after the installation

Because I connect to the internet sometimes using ethernet, sometimes using modem I need to edit the file /etc/ppp/options
and added the line
replacedefaultroute

to automate the replacement of default route when I am using dial-up connection.

After that you can go to yast2 and add the phone number, username and password for your Internet Provider.

You can dial the isp using wvdial (must edit /etc/wvdial.conf first) or using the modem lights panel applet.
To use the modem lights panel applet to dial you need to set the connection and disconnection command.
The connection command is
/etc/sysconfig/network/scripts/ifup-ppp
and the disconnection command is
etc/sysconfig/network/scripts/ifdown-ppp
