That's interesting - it does look like it's
possible to bias & jumper
the inputs (RXD & CTS) on this equipment so that it protects the
receivers. Unfortunately the documentation I've got for this particular
board isn't high on detail; I've got some docs on later revisions though
so will check those. From what I gather, it should be jumper-selectable
to talk to RS232C, RS422, or RS423.
I'm not intimately familiar with the spec, but isn't RS423 very similar
to RS232?
