00009 Before to use this example, ensure that you an hyperterminal installed on your
00010 computer. More info here: https://developer.mbed.org/handbook/Terminals

00012 The default serial comm port uses the SERIAL_TX and SERIAL_RX pins (see their
00013 definition in the PinNames.h file).
00014 
00015 The default serial configuration in this case is 9600 bauds, 8-bit data, no parity
00016 
00017 If you want to change the baudrate for example, you have to redeclare the
00018 serial object in your code:
00019 
00020 Serial pc(SERIAL_TX, SERIAL_RX);
00021 
00022 Then, you can modify the baudrate and print like this:
00023 
00024 pc.baud(115200);
00025 pc.printf("Hello World !\n");
