+ * First, add #inclued "m_printf.h" to your component.
+ * Sencond, use _printf() function in the m_printf.h to print what you want
+ * to see.
+ * attention: don't forget to start your serialport, and just initialization.
+ * The serialport baudrate is at 57600, and you can choose a terminal to watch
+ * the output, for example, cutecom in linux.
+ * For more information see www.eistec.se.

+ * Modification to adopt printf for Mulle-TinyOS is made by
