string: Screen code of the terminal, containing 1 to 15 case-insensitive characters.

Use the menu screencode command to configure a menu screen code.

Use the undo menu screencode command to remove the menu screen code.

By default, no such a screen code is configured.

Some types of terminals provide the screen saving function. When such a terminal 
receives a specific screen code, such as E!10Q (for details about screen codes, refer 
to the related terminal manuals), it saves the current interface and switch to the 
corresponding screen.

Note that this function requires terminal support and the screen code configured 
on the router and that specified on the terminal must be the same. Screen codes 
vary with terminal types. For details, refer to the corresponding terminal manuals. 
For example, Start terminals support E!8Q, E!9Q, E!10Q, E!11Q, E!12Q, and 
E!13Q.

# Configure a menu screencode of E!10Q.

<Sysname> system-view

Use the print connection-info command to enable the printing of terminal 
connection information on the terminal.

Use the undo print connection-info command to disable the printing of 
terminal connection information.

By default, terminal connection information is printed on the terminal.

To facilitate your operation, after a TCP connection is established between the 
terminal and the FEP, the terminal will display a message indicating that the 
connection is successful. To disable the prompt message from being displayed, use 
the undo print connection-info command.

Make sure you enable the router to print characters on the terminal before using 
this command.
