- Chapter Overview
-
- This chapter introduces and describes the basic steps involved in
- using NCSA Telnet for the IBM PC:
-
- Ñ starting the program
- Ñ setting the terminal type
- Ñ opening and closing a telnet connection
-
- The chapter assumes that your system or network administrator
- has installed NCSA Telnet on your system, assigned an IP
- address to your IBM PC, and given you a login name and password
- for the computer to which you want to connect. For information
- regarding installation and customization procedures, refer to
- Chapter 7, "Installation and Configuration."
-
- If you require additional information regarding the IBM interface
- or command line structure, please refer to your IBM PC user's
- guide.
-
-
- Starting the Program
-
- To run NCSA Telnet from the PC command line, from any
- subdirectory, enter:
-
- C:\ > telnet machinename
-
- This command initiates a connection to the remote computer with
- the name given as the machinename parameter. Normally the
- host machine immediately prompts you for a login name and
- password to begin the session.
-
- NCSA Telnet emulates a VT100 terminal. When you log in to a
- host, the host operating system does not know what type of terminal
- you are using. Consult the operating system manual for how to set
- terminal type and try setting it to VT100 or VT102. For systems that
- do not support VT100 (such as many UNIX systems), use VT100,
- which is compatible with VT102 emulators. These examples show
- how to set the terminal type for two popular operating systems,
- UNIX (using the C shell) and VAX/VMS.
-
- newton% set term=vt100;tset For UNIX hosts.
-
- B$ SET TERM/INQ For VAX/VMS hosts.
-
- Using the Help Screen
-
- For a command summary, press ALT-H. A one-screen summary
- of command keys appears, as shown in Figure 1.1. The online help
- summary serves as your quick reference to the command keys.

-
- Quitting NCSA Telnet
-
- To exit the program, log out of the host machine using the
- appropriate logout procedure for that machine. If you have
- concurrent sessions with more than one machine, you must log out
- of each machine. Then NCSA Telnet exits and the DOS prompt is
- displayed.
-
- If one of the hosts crashes, or a session is otherwise hung up, press
- ALT-X. NCSA Telnet first prompts you for confirmation and then
- attempts to close the session while preserving your other live
- sessions.
-
- When all else fails, and it appears that all of the connections are
- completely jammed, press CTRL-Shift-F3 to abort the program.
- Only use CTRL-Shift-F3 as a last resort.
-
- Pressing CTRL-C or CTRL-BREAK sends a CTRL-C to the host.
- You can neither use these commands to break out of NCSA Telnet,
- nor end your session.
