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
may exist between the Escape character and the Escape key.
The Telnet escape character is a key combination, the
simultaneously, that returns you to the Telnet prompt while leaving the connection
to the switcher intact.
The Escape key is the
Local echo
Once connected to the 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 local_echo and then press [Enter] before you open the
connection to the switcher.
With local echo turned on, keystrokes and the switcher's responses 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 local 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
local 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 local echo by typing unset local_echo and then pressing
[Enter] at the Telnet prompt. If you are connected to the switcher and need to
access the Telnet prompt to turn local echo off, type the Escape character (
Set carriage return-line feed
Unless commanded otherwise, Telnet transmits a line feed character only (no
carriage return) to the connected switcher when you press the
correct setting for SIS communication with the switcher. The Telnet set crlf
command forces Telnet to transmit carriage return and line feed characters when
is pressed, but if crlf is set, the SIS link with the switcher does not function
