connecting Sparkfun RS485 breakout to Xbee Pro modem

I am trying to connect Sparkfun RS485 breakout to Xbee Pro modem. Since the RS485 breakout uses the SP3485 RS-485 transceiver IC which has its RTS pin to control the data flow I assumed that this signal should be obtained from the Xbee RTS (DIO6), or CTS (DIO7). Although both IOs where configured as RTS and CTS respectively, they fail to show any change in their status when data sent (from PC) or received from another Xbee..
Has any one tried this type of connection ? and can offer advise with tat regard.
