After testing with genuine arduino uno I could not make
it to work reliably using the original baudrate 38400 on
Windows 7. Linux worked OK, but Windows 7 inserted extra 2
bytes 0xFE or 0xFF at the beginnig of the serial communication
(at least that's what arduino read from the serial line).
Baudrate 57600 so far had no issue, another reliable option
seem to be 9600.
This fixes an issue with Arduino IDE which opens all .c files
(even unrelated) in the same directory when the .ino file is opened.
Fixes compilation error described in issue #10
