How to set uart4 whether to use software control/ Hardware control on IMX53(Android ICS build from linaro)

[poornat]

Hi,

  I am using uart4 which is muxed on imx53 qsb start-R platform working with ICS from linaro. I have set macros in a way that uart4 is up. But I couldnt specify which type of control its using and how to change that control.

  The macros which I am using are as follows

MX53_PAD_CSI0_DAT12__UART4_TXD_MUX,

MX53_PAD_CSI0_DAT13__UART4_RXD_MUX,

MX53_PAD_CSI0_DAT17__UART4_CTS,

MX53_PAD_CSI0_DAT16__UART4_RTS,

Generally cts pin is used for control uart right? How to set some kind of control(s/w or h/w), and that will help me in my work.,,,

Thank you.

Waiting for a useful better answer.

You should specify the flow control to be used from your application using the CRTSCTS flag.
