1.2.3 Synchronous Information Output

Synchronous information output refers to the feature that if the user's input is
interrupted by system output, then after the completion of system output the system will
display a command line prompt and your input so far, and you can continue your
operations from where you were stopped.
You can use the info-center synchronous command to enable synchronous
information output. For the detailed description of this function, refer to Information
Center Configuration.

1.2.4 undo Form of a Command

Adding the keyword undo can form an undo command. Almost every configuration
command has the undo form. undo commands are generally used to restore the
system default, disable a function or cancel a configuration. For example, the
info-center enable command is used to enable the information center, while the undo
info-center enable command is used to disable the information center. (By default, the
information center is enabled.)
