(It unfortunately can't be configured as a host or -on-the-go device). By default, the peripheral is configured for two -uses: first, to receive sketch/program uploads from the :ref:`IDE -<ide>`, and second, to emulate a regular serial port for use as a -terminal (text read/write). - -The emulated terminal is relatively slow and inefficient; it is best -for transferring data at regular serial speeds (kilobaud). Library -support for accessing the emulated terminal is available at the -:ref:`SerialUSB <lang-serialusb>` reference. - -The SerialUSB channel is used with the :ref:`Maple bootloader -<bootloader>` to reprogram the board: a :ref:`magic sequence of -control line toggles and transmitted data <bootloader-rev3>` causes a -Maple to reset itself and enter bootloader mode. As an unfortunate -consequence, the auto-reset will not work if the IDE can not access -the serial port, either due to a conflict with another program (serial -monitor) or because the interface has been disabled from the Maple -side (through :ref:`SerialUSB.end() <lang-serialusb-end>`).
