So I'm clear on how you interpret these,
am I correct with the following?

RTS active = on before send, off after send (RTS enables driver)
CTS ignored (2 wire mode, no CTS)

So maybe the extra control fields would be:
CRTSONTX - RTS on before send, off after send
CTXONCTS - wait for CTS before sending
