PPP makes your computer look like a host computer to other Internet users. Some systems come with software such as Internet Explorer, some do not. Check with your vendor if you are not sure. If you already have one browser, you can download others, once you have a World Wide Web connection.
Many sites are accessible in terminal mode only.
If you do, you have not established a PPP connection. Recheck the setup, especially your user name and password. Now you need to launch an Internet application. During a telnet session, you will be using the other computer in terminal mode. You can set up Netscape to launch a telnet session when you follow a link from a Web page to a terminal-based site such as an online library catalog.
