Working RS485 sketches wanted

With Nicks code above (all be it played with by me)
can someone please tell me how i can get to serial.print the received slave message from the master.
it obviously receives somthing as the Led on pin d13 does not light up indicating that there is no error and that the messege was acknowledged.

I would like the slave to pass messages back when polled and i belive this is already in place, i would like to be able to have several bytes sent in the return message which can be written to variable so that i can output them to the Host (pc connected to master module).
thanks
J.
