+Before to use this example, ensure that you an hyperterminal installed on your computer. 
+More info here: https://developer.mbed.org/handbook/Terminals
+The default serial comm port uses the SERIAL_TX and SERIAL_RX pins (see their definition in the PinNames.h file).
+The default serial configuration in this case is 9600 bauds, 8-bit data, no parity. 
+If you want to change the baudrate for example, you have to redeclare the
+serial object in your code:
+
+Serial pc(SERIAL_TX, SERIAL_RX);
+
+Then, you can modify the baudrate and print like this:
 
-int main() {
+pc.baud(115200);
+pc.printf("Hello World !\n");
