welcome to LQ
I think you are looking for kppp
(one of the menu)
or start a terminal and type kppp <enter>
other issue is whether your modem will work
post modem type (after you have done some searches)
PS: try to make thread title more comprehensive and meaningfull next time please
It will be a steep but rewarding curve.
See lq bookmark for newbie admin guide and search for rute as well.
Look also at distro documentation
Happy linux, happy learning
Edit 2: if you run as root (only for admin thing)
open a terminal
This should list your modem
Edit 3: There is some modem / connection configuration in suse
Did you try to launch yast (i think it is)
