Upgrading the firmware on our Moxa NPort 5610-8 from 3.3 to 3.5 has apparently solved our problems - we have been running for almost a week now without ReplyTimeouts or similar errors.

We observe frequent StreamDevice ReplyTimeouts when communicating
through a Moxa serial device server.  Details follow.  We ask
whether this is expected (or can be mitigated) given our conditions.
We wonder whether we should use some other communication method
(USB to serial adaptors, for example).
