The serial core + 8250_omap driver automatically prevent tx fifo overflow; you don't have to worry about overrunning the fifo when writing. Are you observing overruns at the receiver with CRTSCTS on? Is there a message or are you observing data corruption? Is the receiver also a BBB or something else? What baud rate are you using?
