			 connection; when followed by a ``^Z'' it will
			 suspend the tteellnneett command.  The initial state is
			 to have the rrllooggiinn escape character disabled.

	       ssttaarrtt	 If the TELNET TOGGLE-FLOW-CONTROL option has been
			 enabled, then this character is taken to be the
			 terminal's ssttaarrtt character.  The initial value for
			 the kill character is taken to be the terminal's
			 ssttaarrtt character.

	       ssttoopp	 If the TELNET TOGGLE-FLOW-CONTROL option has been
			 enabled, then this character is taken to be the
			 terminal's ssttoopp character.  The initial value for
			 the kill character is taken to be the terminal's
			 ssttoopp character.

	       ssuusspp	 If tteellnneett is in llooccaallcchhaarrss mode, or LINEMODE is
			 enabled, and the ssuussppeenndd character is typed, a
			 TELNET SUSP sequence (see sseenndd ssuusspp above) is sent
			 to the remote host.  The initial value for the
			 suspend character is taken to be the terminal's
			 ssuussppeenndd character.

	       ttrraacceeffiillee
			 This is the file to which the output, caused by
			 nneettddaattaa,, tteerrmmddaattaa,, or ooppttiioonn tracing being TRUE,
			 will be written.  If it is set to ``--'', then
			 tracing information will be written to standard
			 output (the default).

	       wwoorrddeerraassee
			 If tteellnneett is operating in LINEMODE or ``old line
			 by line`` mode, then this character is taken to be
			 the terminal's wwoorrddeerraassee character.  The initial
			 value for the worderase character is taken to be
			 the terminal's wwoorrddeerraassee character.

	       ??	 Displays the legal sseett (uunnsseett) commands.

     ssllcc _s_t_a_t_e
	       The ssllcc command (Set Local Characters) is used to set or
	       change the state of the the special characters when the
	       TELNET LINEMODE option has been enabled.  Special characters
	       are characters that get mapped to TELNET commands sequences
	       (like iipp or qquuiitt) or line editing characters (like eerraassee and
	       kkiillll).  By default, the local special characters are export-
	       ed.

	       eexxppoorrtt	 Switch to the local defaults for the special char-
			 acters.  The local default characters are those of
			 the local terminal at the time when tteellnneett was
			 started.

	       iimmppoorrtt	 Switch to the remote defaults for the special
			 characters.  The remote default characters are
			 those of the remote system at the time when the
			 TELNET connection was established.

	       cchheecckk	 Verify the current settings for the current spe-
			 cial characters.  The remote side is requested to
			 send all the current special character settings,
			 and if there are any discrepancies with the local
			 side, the local side will switch to the remote
			 value.

	       ??	 Prints out help information for the ssllcc command.

     ssttaattuuss    Show the current status of tteellnneett.  This includes the peer
	       one is connected to, as well as the current mode.

     ttooggggllee _a_r_g_u_m_e_n_t_s ...
	       Toggle (between TRUE and FALSE) various flags that control
	       how tteellnneett responds to events.  These flags may be set ex-
	       plicitly to TRUE or FALSE using the sseett and uunnsseett commands
	       listed above.  More than one argument may be specified.	The
	       state of these flags may be interrogated with the ddiissppllaayy
	       command.  Valid arguments are:

	       aauutthhddeebbuugg   Turn on debugging information for the authenti-
			   cation code.

	       aauuttoofflluusshh   If aauuttoofflluusshh and llooccaallcchhaarrss are both TRUE, then
			   when the aaoo, or qquuiitt characters are recognized
			   (and transformed into TELNET sequences; see sseett
			   above for details), tteellnneett refuses to display
			   any data on the user's terminal until the remote
			   system acknowledges (via a TELNET TIMING MARK
			   option) that it has processed those TELNET se-
			   quences.  The initial value for this toggle is
			   TRUE if the terminal user had not done an "stty
			   noflsh", otherwise FALSE (see stty(1)).

	       aauuttooeennccrryypptt

	       aauuttooddeeccrryypptt
			   When the TELNET ENCRYPTION option is negotiated,
			   by default the actual encryption (decryption) of
			   the data stream does not automatically start.
			   The aauuttooeennccrryypptt ((aauuttooddeeccrryypptt)) command states
			   that encryption of the output (input) stream
			   should be enabled as soon as possible.

	       aauuttoollooggiinn   If the TELNET AUTHENTICATION option is supported
			   by the remote side, then tteellnneett will attempt to
			   use it to perform automatic authentication.	If
			   the AUTHENTICATION option is not supported, then
			   the users login name will be propagated via the
			   TELNET ENVIRON option.  This command is the same
			   as specifying --aa option on the ooppeenn command.

	       aauuttoossyynncchh   If aauuttoossyynncchh and llooccaallcchhaarrss are both TRUE, then
			   when either the iinnttrr or qquuiitt characters is typed
			   (see sseett above for descriptions of the iinnttrr and
			   qquuiitt characters), the resulting TELNET sequence
			   sent is followed by the TELNET SYNCH sequence.
			   This procedure sshhoouulldd cause the remote system to
			   begin throwing away all previously typed input
			   until both of the TELNET sequences have been
			   read and acted upon.  The initial value of this
			   toggle is FALSE.

	       bbiinnaarryy	   Enable or disable the TELNET BINARY option on
			   both input and output.

	       iinnbbiinnaarryy    Enable or disable the TELNET BINARY option on
			   input.

	       oouuttbbiinnaarryy   Enable or disable the TELNET BINARY option on
			   output.

	       ccrrllff	   If this is TRUE, then carriage returns will be
			   sent as <CR><LF>.  If this is FALSE, then car-
			   riage returns will be send as <CR><NUL>.  The
			   initial value for this toggle is FALSE.

	       ccrrmmoodd	   Toggle carriage return mode.  When this mode is
			   enabled, most carriage return characters re-
			   ceived from the remote host will be mapped into
			   a carriage return followed by a line feed.  This
			   mode does not affect those characters typed by
			   the user, only those received from the remote
			   host.  This mode is not very useful unless the
			   remote host only sends carriage return, but nev-
			   er line feed.  The initial value for this toggle
			   is FALSE.

	       ddeebbuugg	   Toggles socket level debugging (useful only to
			   the ssuuppeerr uusseerr).  The initial value for this
			   toggle is FALSE.

	       eennccddeebbuugg    Turn on debugging information for the encryption
			   code.

	       llooccaallcchhaarrss
			   If this is TRUE, then the fflluusshh, iinntteerrrruupptt,
			   qquuiitt, eerraassee, and kkiillll characters (see sseett above)
			   are recognized locally, and transformed into
			   (hopefully) appropriate TELNET control sequences
			   (respectively aaoo, iipp, bbrrkk, eecc, and eell; see sseenndd
			   above).  The initial value for this toggle is
			   TRUE in ``old line by line'' mode, and FALSE in
			   ``character at a time'' mode.  When the LINEMODE
			   option is enabled, the value of llooccaallcchhaarrss is
			   ignored, and assumed to always be TRUE.  If
			   LINEMODE has ever been enabled, then qquuiitt is
			   sent as aabboorrtt, and eeooff aanndd are sent as eeooff aanndd
			   ssuusspp, see sseenndd above).

	       nneettddaattaa	   Toggles the display of all network data (in hex-
			   adecimal format).  The initial value for this
			   toggle is FALSE.

	       ooppttiioonnss	   Toggles the display of some internal tteellnneett pro-
			   tocol processing (having to do with TELNET op-
			   tions).  The initial value for this toggle is
			   FALSE.

	       pprreettttyydduummpp
			   When the nneettddaattaa or tteerrmmddaattaa toggle is enabled,
			   if pprreettttyydduummpp is enabled the output from the
			   nneettddaattaa and tteerrmmddaattaa command will be formated in
			   a more user readable format.  Spaces are put
			   between each character in the output, and the
			   beginning of any TELNET escape sequence is pre-
			   ceded by a '*' to aid in locating them.

	       sskkiipprrcc	   When the sskkiipprrcc toggle is TRUE, then tteellnneett will
			   skip the reading of the ._t_e_l_n_e_t_r_c file in the
			   users home directory when connections are
			   opened.  The initial value for this toggle is
			   FALSE.

	       tteerrmmddaattaa    Toggles the display of all terminal data (in
			   hexadecimal format).  The initial value for this
			   toggle is FALSE.

	       vveerrbboossee__eennccrryypptt
			   When the vveerrbboossee__eennccrryypptt toggle is TRUE, then
			   tteellnneett will print out a message each time en-
			   cryption is enabled or disabled.  The initial
			   value for this toggle is FALSE.

	       ??	   Displays the legal ttooggggllee commands.

     zz	       Suspend tteellnneett.	This command only works when the user is
	       using the csh(1).

     !! [_c_o_m_m_a_n_d]
	       Execute a single command in a subshell on the local system.
	       If ccoommmmaanndd is omitted, then an interactive subshell is in-
	       voked.

     ?? [_c_o_m_m_a_n_d]
	       Get help.  With no arguments, tteellnneett prints a help summary.
	       If a command is specified, tteellnneett will print the help infor-
	       mation for just that command.

EENNVVIIRROONNMMEENNTT
     TTeellnneett uses at least the HOME, SHELL, DISPLAY, and TERM environment
     variables.  Other environment variables may be propagated to the other
     side via the TELNET ENVIRON option.

HHIISSTTOORRYY
     TTeellnneett appeared in 4.2 BSD.

NNOOTTEESS
     On some remote systems, echo has to be turned off manually when in
     ``old line by line'' mode.

     In ``old line by line'' mode or LINEMODE the terminal's eeooff character
     is only recognized (and sent to the remote system) when it is the
     first character on a line.
