Launching your connection runs two other processes.
The high-level data link control (HDLC) protocol controls the flow of information
between your computer and your ISP??™s server, and the chat routine communicates with
the modem, dials the number, and reports on the status of your connection (or occasional
lack thereof).
If you want to confirm that pppd is installed, log in as SuperUser (su) and run pppd with
the ??”help argument. You??™ll see the many parameters you can use to tune your connection,
but veering from the defaults can be risky.
CAUTION
Some modems still have a software interface that will not work under Linux. See
Chapter 2, ???Preparing to Install openSUSE,??? for more information on Winmodems.
Using YaST to Set Up Your Dial-up Connection
YaST??™s Network Devices section manages setup wizards for several types of network
connections:
. Modem
. Network card
. ISDN
. DSL
Although very similar, there are some distinctions. In this section, we??™ll cover the modem
connection. The DSL connection will be in the next section, and the other networking
protocols will be covered in Chapter 25.
