  Log:
  SVN rev 218000 on 2011-01-28 00:22:03Z by marcel
  
  In uart_tty_outwakeup(), check CTS/RTS flow control settings and
  prevent sending data when CTS is de-asserted.
  In uart_tty_intr(), call uart_tty_outwakeup() when the CTS signal
  changed, knowing that uart_tty_outwakeup() will do the right
  thing for flow control. This avoids redundant conditionals.
