Local echo
Once connected to the MTPX Plus 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 MTPX Plus switcher and
need to access the Telnet prompt to turn local echo off, type the Escape character
(

).

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

Close
To close the link to the switcher, access the Telnet prompt by typing the Escape
