What did you try, precisely? What, exactly, was the error message that it returned? – John1024 – 2014-04-30T05:47:50.423

The stty command handles that:

sudo stty -F /dev/ttyS0 9600

You can confirm that you succeeded in changing the baud rate by asking stty to print out the current settings with:

sudo stty -F /dev/ttyS0 -a

See man stty for more details.
