Error Prompts; Command Edit - 3Com WX3000 Series Operation Manual

By default, the CLI can store up to 10 latest executed commands for each user. You can view the
command history by performing the operations listed in
Table 1-3 View history commands
Purpose
Display the latest executed
history commands
Recall the previous history
command
Recall the next history
command
Because the Windows 9x HyperTerminal explains the up and down arrow keys in a different way,
the two keys are invalid when you access history commands in a Windows 9x HyperTerminal
environment. However, you can use Ctrl+P and Ctrl+N instead to achieve the same purpose.
When you enter the same command multiple times consecutively, only one history command entry
is created by the command line interface.
