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.

Error Prompts

If a command passes the syntax check, it will be successfully executed; otherwise, an error message will be displayed. Table 1-4 lists the common error messages.
