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 ‚Üë
and ‚Üì 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.
All the input commands by users can be correctly executed, if they have passed
the grammar check. Otherwise, error messages will be reported to users. The
common error messages are listed in the following table.
