Unfortunately we need the RS422 stuff - that's the reason for using the
DSC-200/300 card.

Thanks for the comments and feedback - I'll take another look at things in

significant amount of new code to be written, I suspect that the work will
be deemed too time consuming by those who call the shots. We'll see.
