t
telnet(1) telnet(1)
see set above for details), telnet 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 sequences. The initial value for this
toggle is TRUE.
autosynch
If autosynch and localchars are both TRUE, when either the intr or
quit character is typed (see set above for descriptions of the intr and
quit characters), the resulting TELNET sequence sent is followed by the TEL-
NET SYNCH sequence. This procedure should cause the remote system to begin
discarding all previously typed input until both of the TELNET sequences have
been read and acted upon. The initial value of this toggle is FALSE.
binary
Enable or disable the TELNET BINARY option on both input and output. This
option should be enabled in order to send and receive 8-bit characters to and
from the TELNET server.
crlf
If TRUE, end-of-line sequences are sent as an ASCII carriage-return and line-
feed pair. If FALSE, end-of-line sequences are sent as an ASCII carriage-return
and NUL character pair. The initialvalue for this toggle is FALSE.
crmod
Toggle carriage return mode. When this mode is enabled, any carriage return
characters received from the remote host are 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 only required for some hosts that require the client
to do local echoing, but output ‘‘naked’’ carriage returns. The initial value for
this toggle is FALSE.
echo
Toggle local echo mode or remote echo mode. In local echo mode, user input is
echoed to the terminal by the local telnet before being transmitted to the
remote host. In remote echo, any echoing of user input is done by the remote
host. Applications that handle echoing of user input themselves, such as C shell,
Korn shell, and vi (see csh(1), ksh(1), and vi(1)), do not work correctly with
local echo.
options
Toggle viewing of TELNET options processing. When options viewing is enabled,
all TELNET option negotiations are displayed. Options sent by telnet are
displayed as ‘‘SENT’’, while options received from the TELNET server are
displayed as ‘‘RCVD’’. The initial value for this toggle is FALSE.
netdata
Toggles the display of all network data (in hexadecimal format). The initial
value for this toggle is FALSE.
? Displays the legal toggle commands.
RETURN VALUE
In the event of an error, or if the TELNET connection is closed by the remote host,
telnet returns a
value of 1. Otherwise it returns zero (0).
DIAGNOSTICS
The following diagnostic messages are displayed by
telnet:
Error! Could not retrieve authentication type.
There are two authentication mechanisms used by TELNET. One authentication mechanism is
based on Kerberos and the other is not. The type of authentication mechanism is obtained from
a system file which is updated by inetsvcs_sec . If the system file on either the local host or
the remote host does not contain known authentication types, the above error is displayed.
telnet/tcp: Unknown service
telnet
was unable to find the TELNET service entry in the services(4) database.
