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 responses of the 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.

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 (
