Many SIS commands include the keyboard

Local echo
Once connected to the FOX 4G 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 local_echo and then press
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
at the Telnet prompt. If you are connected to the FOX 4G matrix switcher and
need to access the Telnet prompt to turn local echo off, type the Escape character
