| Using Telnet |
| Telnet is an established method of communicating on the Internet, but unlike the other older methods, it hasn't been replaced by other functions on the World Wide Web. At this writing, many libraries and usergroups are only available through Telnet, so you may find that you have to tackle this technology. Basically, it is the protocol (system of computer rules and formats) that allows you to communicate directly with another, distant computer. The technology allows your keyboard to behave as if it were attached to the other computer and its programs.
For Mac/Windows users, using Telnet, which is UNIX based, is not easy. Not only is the mouse useless (touching it can sometimes even break the connection), but keystrokes may produce very different results from what the label on the key says. (For example, an arrow key may add an unremovable symbol.) If your library or computer lab does not provide detailed written instructions, ask a librarian or technical staff member for help. First determine if you have Telnet on your system. (Colleges with UNIX do; other systems--including commercial online servers--may require that you install additional software.) Get the Telnet address. You usually encounter one when you're on a Website and want to go further, but you may also find what you want at http://www.einet.net/ Write down the address and also the exact letters of the logon (letters that you type in to start the program)--usually a word in all capitals. You may also be given a password and the logoff (letters that you type to exit the program). At the prompt line or the Telnet window of your program, type in the address (the name of the organization or a series of numbers--like a phone number--separated by periods). When you reach the site, you'll first be conscious of its simple look--just plain typeface. You may need to adjust the screen size; check the top of the screen for Options. Read the initial directions and write down (if one is given) the "escape character" (usually three keyboard symbols, such as +++, that you must use when you give commands at this site). If you don't have it already, write down the logoff to type in for the end of your session. Using all uppercase, type in the required logon, and follow scrupulously the directions on the screen each time. Unless directed to do otherwise, each time you write a command (such as "OPEN,") you will need to precede the commands with the escape characters and a space. Don't touch any keys until you are instructed to do so. Be sure to type slowly, allowing for the brief time lag it takes for your keystroke to communicate with the other computer. If you make a mistake in typing, sometimes you can Backspace/Delete to fix it, but if not, press Enter/Return and usually the program will allow you to retype. For example, to reach The National Register of Historic Places, you type 165.83.212.245/ in the address window or at the Telnet prompt. You were given the logon (NRIS) when you got the Telnet address (on the home page of the National Register http://www.cr.nps.gov/nr/nrhome.html). Then you enter the letter indicating your choice, and press Enter/Return. Alternatively, type in the escape character or command {/} and then open and the name of the building you want information about. Press Enter/Return. (You will need to press Enter/Return after choices--unless the desired letter or number gives an immediate response.) Be sure to logoff once you have finished. Logoff is {/}QUIT.
