Extron electronics XTP II CrossPoint 1600 User Manual page 166

Once you are logged in, the switcher returns either Login Administrator or Login
User. No further prompts are displayed until you break or disconnect the connection to the
XTP II CrossPoint switcher.
Escape character and Esc key
When Telnet is first started, the utility advises that the Escape character is ' '. Many
Ctrl+]
SIS commands include the keyboard key. Consequently, some confusion may exist
<Esc>
between the Escape character and the Escape key.
The Telnet Escape character is a key combination, the key and the key pressed
<Ctrl> <]>
simultaneously, which returns you to the Telnet prompt while leaving the connection to the
XTP II CrossPoint switcher intact.
The Escape key is the key on the computer keyboard. Use this key for SIS
<Esc>
commands.
Analog echo
Once connected to the XTP II CrossPoint 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 analog_echo and then press < > before you open the connection to the
Enter
switcher.
With analog echo turned on, keystrokes and the responses of the switcher 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 analog 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 analog
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 analog echo by typing unset analog_echo and then pressing < >
Enter
at the Telnet prompt. If you are connected to the XTP II CrossPoint switcher and need to
access the Telnet prompt to turn analog 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 < > key. This is the correct
Enter
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
Enter
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
( + ). At the Telnet prompt, type close, and then press < >.
<Ctrl> <]> Enter
Help
For Telnet command definitions, at the Telnet prompt, type and then press < >.
? Enter
Quit
Exit the Telnet utility by typing and then pressing < > at the Telnet prompt. If you
quit Enter
are connected to the XTP II CrossPoint switcher, access the Telnet prompt by typing the
Escape character ( + ).
