How do I enable InterNiche uart flow control (RTS & CTS)?

I want to enable hardware handshaking so uncommented the two lines in iuart.c :-

 

/* configure for 8,N,1 with flow control */
   MCF_UART_UMR(dev) = ( // MCF_UART_UMR_RXRTS |
                             MCF_UART_UMR_PM_NONE |
                             MCF_UART_UMR_BC_8 );
                            
   MCF_UART_UMR(dev) = ( MCF_UART_UMR_CM_NORMAL |
//                             MCF_UART_UMR_TXCTS |
                             MCF_UART_UMR_SB_STOP_BITS_1 );

This seems to have no effect.  Is there anything else needs to be done to achieve this?
