 *  \brief   Serial interface voor HvA-Xmegaboard
 *
 *  \details This serial interface doesn't use the drivers of Atmel
 *           The interface uses two \e non circulair buffers for sending and 
 *           receiving the data.
 *           It is based om md_serial.c from J.D.Bakker.
 *
 *           It is a serial interface for the HvA-Xmegaboard (Version 2) with a
 *           Xmega256a3u and Xmega32a4u for programming and the serial interface.
 *           You can use the standard printf, putchar, puts, scanf, getchar, ...
 *           functions.
 *
 *           The baud rate is 115200
