  Mr. van Houten, I could not reach you on the phone number you provided.
Then I found that Hans Linschooten beat me by 15 minutes. Since part of
the discussion is already on the net I decided that this response is
more appropriate than mail. So :

  (As Hans already indicated) The "termio(7)" manual page says :

     DEPENDENCIES
	  Series 800
	       ENQ/ACK protocol	and IENQAK bit are not supported.

  Could you please inform us *why* you need ENQ/ACK? Only very old HP
terminals have only ENQ/ACK. By "old" I mean 197X vintage. All 262X and
newer terminals have both ENQ/ACK (for non-HP-UX/UNIX, etc. systems) and
Xon/Xoff. I *think* the old terminals can even be upgraded to Xon/Xoff if
needed.

  Please call us directly at the Dutch Country Response Center (06-0511).
  You do have a Response Center contract for your 850, don't you? :-)

  While this topic may be of interest to the net, I think you will get
better response times for questions like this by calling your CRC.
  Anyway the response time Hans gave was also not too bad! :-)
