We've evaluated three flavors of serial board for Xenix:

	1.  Computone.  Works fine.  We had to roll our own cables since
	    the board has RJ-11 (phone-like) jacks.  I didn't install it,
	    but it's in use now and I've heard no complaints.  Recommended.

	2.  Emulex.  Works fine.  (It's on my system.)  I got a warm feeling
	    when I saw drivers for SCO 2.1, SCO 2.2, and IBM Xenix included.
	    The manual is shrink-wrapped, intended for insertion in your
	    Xenix manuals.  This is my favorite.  Recommended.
	    (You can configure each port as DCE or DTE, so you don't need
	    null modems for direct connections with computers/terminals.)

	3.  Digiboard.  We got the eight-port intelligent version.  It didn't
	    work -- `more' was broken!!!  I called them and they said `Yes,
	    the programmer(!) is working on that.'  How can you release a
	    Xenix peripheral that breaks `more'?!?!  Also, the only driver
	    was for SCO Xenix 2.2.   Not recommended.

(Note that my machine works fine with _six_ serial ports; the Emulex board
has four and I still use tty1a and tty2a.)

I hope that this info will help potential buyers to steer clear of trouble.

Note that I speak only from _personal_ experience, and your milage may vary,
etc.
