  The particular device I have in my office works. But I don't
  really know if there are variants of this device.

	     I am still the one who told that. In fact when
	     starting the alizé you you got a menu. I discover
	     that on my device you have to click the jaws item
	     to establish a connection between the device and
	     the pc that may be used by brltty. Once jaws is
	     clicked and you start the pc you get a message :
	     "connection non établie 2279" until you get brllty
	     welcome message.

	     Beware Raphaël I am not shure that with very old
	     stuff you might do operations in any order. In
	     fact I always start the alizé, click on jaws and
	     then start the pc.

	     I tried also this options emulation pc but it
	     never gave anything. I suspect that we do not have
	     exactly the same soft on the alizé even if the
	     device itself is the same.

  I know : up to restrictions I mentioned above. In fact I see
  at least three differnces between my situation and Raphaël's
  :

  1. connection via a true serial port vs an adapter

  2. Maybe not exactly the same soft version in the braille
  device.

  3. I am driving this alizé with a brltty 3.9. Do not ask me
  why ! but only because that the pc that still have a serial
  port has an obsolete red hat 8 system on it.
