uart flow control

[sbsrb]

Hi there,
I wanted to add flow control support to my uart port. Current driver disables the flow control by default.
I want to use RTS/CTS flow control, to achieve this, i just have to set MCR[5] =ON (AFCE bit) or is it more than this.

And sorry for asking this question now as i haven' tried anything yet, but i thought may be you can throw some more light on how and what needs to be done to achieve this.

Thanks, Rishi
