.TH TELNET 1 "10 February 1983"
telnet \- user interface to the TELNET protocol
is used to communicate with another host using the TELNET protocol. If
is invoked without arguments, it enters command mode,
indicated by its prompt (\*(lqtelnet>\*(rq).
In this mode, it accepts and executes the commands listed below.
If it is invoked with arguments, it performs an
command (see below) with those arguments.
Once a connection has been opened,
In this mode, text typed is sent to the remote host. To issue
commands when in input mode, precede them with the
\*(lqescape character\*(rq (initially \*(lq^[\*(rq).
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.
\fBopen\fP \fIhost\fP [ \fIport\fP ]
Open a connection to the named host. If the no port number
will attempt to contact a TELNET server at the default port.
The host specification may be either a host name (see
or an Internet address specified in the \*(lqdot notation\*(rq.
Close a TELNET session and return to command mode.
Close any open TELNET session and exit
This command only works when the user is using the
\fBescape\fP [ \fIescape-char\fP ]
\*(lqescape character\*(rq. Control characters may
be specified as \*(lq^\*(rq followed by a single
letter; e.g. \*(lqcontrol-X\*(rq is \*(lq^X\*(rq.

as the state of debugging.
Toggle viewing of TELNET options processing. When
options viewing is enabled, all TELNET option negotiations
will be displayed. Options sent by

received from the TELNET server are displayed as
Toggle carriage return mode. When this mode is enabled
any carriage return characters received from the remote
host will be mapped into a carriage 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 like to ask
the user to do local echoing.
\fB?\fP [ \fIcommand\fP ]
Get help. With no arguments,
If a command is specified,
will print the help information available about the command only.
There is no provision in the standard TELNET protocol
to support ^S/^Q type commands. This implementation
is the standard mechanism used to communicate locally
