1.3.3 History Command of Command Line

Command line interface provides the function similar to that of DosKey. The commands
entered by users can be automatically saved by the command line interface and you
can invoke and execute them at any time later. History command buffer defaults to 10.
The operations are shown in the table below.
Table 1-3 Retrieve history command
Display history command
Retrieve the previous
history command
Retrieve the next history
command
Note:
Cursor keys can be used to retrieve the history commands in Windows 3.X Terminal
and Telnet. However, in Windows 9X HyperTerminal, the cursor keys ↑ and ↓ do not
work, because Windows 9X HyperTerminal defines the two keys differently. In this case,
use the combination keys <Ctrl+P> and <Ctrl+N> instead for the same purpose.
