The two interfaces are provided by the USB. One appears as a USB drive for the user to load new firmware (program), the other is the Virtual COM Port for serial debug messages (debug).
J6 mbed USB Connector , attaches to the ST Micro controller. This provides access to two interfaces, one used to program the mDot and the other for debug messages.
For example programs the baud rate of the serial port is not being configured by libmDot. libmDot holds a configuration baud rate for use by the AT Command firmware, it does not setup the serial for an application.
The default mbed baud rate 9600 is being used.
