Serial Console
==============
These configurations assume that you are using a standard Arduio RS-232
shield with the serial interface with RX on pin D0 and TX on pin D1:
The STM32F469G-DISCO uses USART1 connected to "Virtual COM", so when you
plug it on your computer it will be detected as a USB port (i.e. ttyACM0):

All you need to do after flashing NuttX on this board is use a serial
console tool (minicom, picocom, screen, hyperterminal, teraterm, putty,
etc ) configured to 115200 8n1.
