Commands are case sensitive. You can halt any command by pressing the Break key on a terminal. If
you are using a PC, most terminal emulation programs halt a command when you press the Ctrl and the
Break keys at the same time. If you are using another type of terminal emulator or terminal emulation
software, see the documentation for that product for information on how to send a Break command.
