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.

for the incomplete one and displays it in the next line.
If there is more than one match, you can press Tab repeatedly to display
in cycles all the keywords starting with the character string that you typed.
If there is no match, the system does not modify the incomplete keyword
and displays it again in the next line.
