 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.
