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

but it is connected on a native serial
device, not on a converter.

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.
