On the HyperTerminal of Windows 9X, the cursor key
↑

Windows 9X define the keys differently. In this case, you can replace the cursor key
↑
with
Ctrl+P
.
When you use the history command, note the following:
z
The saved history commands are the same as that those input by users. For example, if
the user inputs an incomplete command, the saved command also is incomplete.
z
If the user runs the same command for several times, the earliest command is saved. If
the command is input in different forms, they are considered as different commands.
z
For example, if the
display ip routing-table
command is run for several times, only one
history command is saved. If the
display ip routing
command and the
display ip
routing-table
command are run, two history commands are saved.
