How to get started on serial ports on the BBB

Hi,

I am little confused about serial ports on the BBB.

How can the BBB be connected to a RS 232 port ?? Do I have to use a USB-serial converter ?? or can this be done using the USART I/O pins on the BBB ?

I have seen a tutorial on adafruit that explains serial ports using python, I would like to use C++ for this, could anyone please point out some tutorials that explain how this can be done.

thanks

From a hardware perspective id you want to connect to a RS232 interface, you will need an RS232 level shifter.

Sure I understand, its not the hardware that is the problem, I need some C++ or C tutorials for the BeagleBone black that can help me.

Which of the USART ports can I use ?? Something that runs by default after power up would be good.

thanks
