Work through these exercises. There is nothing that needs to be handed in.

Starting and Configuring Telnet

There are two ways to do this. Try both.

Telnetting Directly

1. Open the Internet folder on the OS/2 desktop. Find the telnet application within the folder and start it.

2. If you want, you can increase the font size. From ``Options,'' choose ``Fonts...'' SystemVIO 10x18 is a good choice. Don't forget to increase the size of the telnet window after you've changed the font.

3. To connect to a telnet server, choose ``Connection,'' then ``Open session...'' Set the emulator to VT100. Host name should be filled in with the appropriate host name. Also, enter a port if one is given, otherwise the port field should be blank.

4. Click ``OK'' to open the connection.

Telnetting from a WWW Browser

1. Start Netscape Navigator.

2. Netscape Navigator is configured to start telnet if a telnet URL is entered. For example, try entering telnet://martini.eecs.umich.edu:3000. (The last period is not part of the URL.) Note that you have to combine the access method, host name, and port (if other than the default) into the URL.

3. Once telnet starts, it can be configured following the instructions from the previous section.

4. Once you've finished and closed the session, close telnet. Find the Windows icon in the lower left-hand corner of the desktop and open it to return to Netscape Navigator.
