PXI-8433/4 RTS/CTS line control


  We have custom firmware for the 485 communication on our product.  It uses the RTS line as a write enable and the CTS line as a loop back of the RTS.  We were sold this PXI-8433/4 with the sales rep indicating that this product could do this.  I am looking for a programming example of how to setup a port to read/write (set high/low) for a given port when i send a message over the line.  Anyone have any idea / direction / help?

Hmm wording wasn't great.  What we need to do is set the flow control so that the RTS line goes high and stays high for our serial stream.
