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.
