I have the terminal set 4800n1, and the CPU switch and jumper settings seem
to agree (what I can see), though there must be something that is not
agreeing.

 The confusing bit (for me ), is that there are two RX wires, RCV+ and RCV-,
what is the convention for using these, with say a VT320? is one of them
normally connected to earth? At th moment, I have the RCV+ connected to the
terminals TXD, and RCV- is earthed (how I found the system) - is this
correct?

Jim.
