1. Prerequisites

Before attempting to use PPP, you must check two things.

1.1 Ensure that the Modem Works

There are no instructions here for troubleshooting serial links. Test the modem installation using a terminal program such as minicom. If you can dial the modem, and log into a remote site, (DAS, for example) the modem should work fine.

1.2 Ensure that the Networking Tools are Installed

At a minimum, you need: ifconfig, and route. These will suffice to get the link set up.

To actually use the link, you'll need things like telnet, rlogin, a web browser, an ftp client, or the like.
