      NAME
           telnet - user interface to the TELNET protocol

      SYNTAX
           telnet [ host [ port ] ]

      DESCRIPTION
           Telnet is used to communicate with another host using the
           TELNET protocol.  If telnet is invoked without arguments, it
           enters command mode, indicated by its prompt (telnet>).  In
           this mode, it accepts and executes the commands listed
           below.  If it is invoked with arguments, it performs an open
           command (see below) with those arguments.

           Once a connection has been opened, telnet enters input mode.
           In this mode, any text typed is sent to the remote host.  To
           issue telnet commands when in input mode, precede them with
           the telnet escape character (initially ^[).  When in command
           mode, the normal terminal editing conventions are available.

           The following commands are available.  Only enough of each
           command to uniquely identify it need be typed.

           open host [ port ]
                Open a connection to the named host.  If the no port
                number is specified, telnet will attempt to contact a
                TELNET server at the default port.  The host
                specification may be either a host name (see hosts(4))
                or an Internet address specified in the dot notation.

           close
                Close a TELNET session and return to command mode.

           quit Close any open TELNET session and exit telnet.

           z    Suspend telnet.  This command only works when the user
                is using the csh(1).

           escape [ escape-char ]
                Set the telnet escape character.  Control characters
                may be specified as ^ followed by a single letter; e.g.
                control-X is ^X.

           status
                Show the current status of telnet.  This includes the
                peer one is connected to, as well as the state of
                debugging.

           options
                Toggle on and off the display of the TELNET options
                being processed.  When option viewing is enabled, all
                TELNET option negotiations will be displayed.  Options

                sent by telnet are displayed as SENT, while options
                received from the TELNET server are displayed as RCVD.

           crmod
                Toggle return mode.  When this mode is enabled, any
                return characters received from the remote host will be
                mapped into a return and a line feed.  This mode does
                not affect those characters typed by the user, only
                those received.  This mode is not very useful, but is
                required for some hosts that ask the user to do local
                echoing.

           ? [ command ]
                Get help.  With no arguments, telnet prints a help
                summary.  If a command is specified, telnet will print
                the help information available about the command only.

      BUGS
           This implementation is very simple because rlogin(1) is the
           standard mechanism used to communicate locally with hosts.
