Operating using Telnet

Local echo
Once your computer is connected to the DXP switcher, by default Telnet does not display

responses are displayed on the screen. To command Telnet to show all keystrokes, enter

With local echo turned on, keystrokes and the switcher responses are displayed on the

Note that all keystrokes are displayed, even those that should be masked, such as the
