If you're using Windows 95, or have acquired Telnet client software, you can telnet from a DOS prompt or from the Run dialog box. You just type "telnet," followed by a space and the Telnet address. Do not include the colon and slash marks "://" between "telnet" and the address. For example, to telnet to Hubble Space Telescope information, type telnet stinfo.hq.eso.org and type stinfo at the log-in prompt.
