Local echo, Close, Help, Quit | Extron electronic Ultra Series

Local echo

Once connected to the CrossPoint or MAV 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 CrossPoint or MAV switcher and need to access the Telnet prompt to turn local 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 switcher when you press the

Enter key. This is

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

Enter

is pressed, but if crlf is set, the SIS link with the switcher does not function

properly.

Close

To close the link to the 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 CrossPoint or MAV switcher, access the Telnet prompt by typing the Escape character ( Ctrl + ] ).
