Connect the CTS and RTS to the application which uses these pins. In our case the only signals which we need are Tx and Rx. The processors can be configured to use the other signals, but then you need to dig into the processor manuals and into the details of SW drivers. (I do not mean RISC5 here, but rather Blackfin or ARM.) The simplest configuration is as shown in the schematics. I copied it from Analog Devices years ago and used it ever since.

It works, if the device driver sets the internal processor registers the proper way, what all sane device drivers do.
