Undo Form Of A Command; Controlling Cli Display - 3Com 4500 PWR 26-Port Configuration Manual

You may use arrow keys to access history commands in Windows 200X and XP Terminal or Telnet.
However, the up and down arrow keys are invalid in Windows 9X HyperTerminal, because they are
defined differently. You can press Ctrl+P or Ctrl+N instead.
Note that:
The commands saved in the history command buffer are in the same format in which you typed the
commands. If you typed an incomplete command, the command saved in the history command
buffer is also an incomplete one.
If you execute the same command repeatedly, the device saves only the earliest record. However,
if you execute the same command in different formats, the system saves them as different
commands. For example, if you execute the display cu command repeatedly, the system saves
only one command in the history command buffer. If you execute the command in the format of
display cu and display current-configuration respectively, the system saves them as two
commands.
By default, the CLI can save up to ten commands for each user. You can use the
history-command max-size command to set the capacity of the history command buffer for the
current user interface (For more information about the history-command max-size command,
see Login Configuration).

Undo Form of a Command

The undo form of a command typically restores the default, disables a function, or removes a
configuration.
Most of configuration commands have their own undo form.
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.
