If you cannot access the USB serial interface, try unplugging and replugging the USB cable (and do not run slcand after).
 - By default, you should not expect any serial interface to support the "backspace" character. If you made a mistake while typing a command, you need to restart from the beginning. RAMN's :ref:`usb_cli` supports backspaces to be more user-friendly.
