Escape character and Esc key
When Telnet is first started, the utility advises that the Escape character is ‘
Ctrl
+
]
’. Many
SIS commands include the keyboard
<Esc>
key. Consequently, some confusion may exist
between the Escape character and the Escape key.
The Telnet Escape character is a key combination, the
<Ctrl>
key and the
<]>
key pressed
simultaneously, which returns you to the Telnet prompt while leaving the connection to the
XTP CrossPoint Series matrix switcher intact.
The Escape key is the
<Esc>
key on the computer keyboard. Use this key for SIS
commands.
Analog echo
Once connected to the XTP CrossPoint Series matrix switcher, by default, Telnet does not
display your keystrokes on the screen. SIS commands are typed in blindly and only the
SIS responses are displayed on the screen. To command Telnet to show keystrokes, at
the Telnet prompt, type
set analog_echo
and then press
<Enter>
before you open the
connection to the matrix switcher.
With analog echo turned on, keystrokes and the responses of the matrix switcher are
displayed on the same line. For example:
1*1!In1 Out1 All
, where
1*1!
is the SIS
command and
In1 Out1 All
is the response.
With analog echo turned on, all keystrokes are displayed, even those that should be
masked, such as the password entry. For example, when entering a password with analog
echo turned on, you see a display such as
a*d*m*i*n*
, where admin is the keyed in
password and
*****
is the masked response.
You can turn off analog echo by typing
unset analog_echo
and then pressing
<Enter>
at the Telnet prompt. If you are connected to the XTP CrossPoint Series matrix switcher
and need to access the Telnet prompt to turn analog echo off, type the Escape character
(
<Ctrl>
+
<]>
).
Set carriage return-line feed
Unless commanded otherwise, Telnet transmits a line feed character only (no carriage
return) to the connected matrix switcher when you press the
<Enter>
key. This is the
correct setting for SIS communication with the matrix switcher. The Telnet
set crlf
command forces Telnet to transmit carriage return and line feed characters when
<Enter>
is pressed, but if crlf is set, the SIS link with the matrix switcher does not function properly.
Close
To close the link to the matrix switcher, access the Telnet prompt by typing the Escape
character (
<Ctrl>
+
<]>
). At the Telnet prompt, type
close
, and then press
<Enter>
.
Help
For Telnet command definitions, at the Telnet prompt, type
?
and then press
<Enter>
.
Quit
Exit the Telnet utility by typing
quit
and then pressing
<Enter>
at the Telnet prompt. If you
are connected to the XTP CrossPoint Series matrix switcher, access the Telnet prompt by
typing the Escape character (
<Ctrl>
+
<]>
).
