The group I work with has done about 8 controllers over the last 3 years.
These all include RS422 async single and/or multi-drop. None of these
controllers are sold individually - they are part of a larger machine.
The protocols are all passing strings around.

These async interfaces are the primary interfaces to these controllers. I
can't imagine spending valuable time futzing with USB or some such modern
scheme, when there's work to be done.
