[BRLTTY] strange behavior udev and systemd

[Sébastien Hinderer]

Hello,

When several instances of BRLTTY are started, each instance that is
asked to run a BrlAPI server will do so and, by default, the servers
will be listening on ocnsecutive TCP ports.

Thus, yes, a client will, by default, connect to the first BrlAPI server
it finds. However, the BRLAPI_HOST environemnt variable can be used to
let clients connect to another BrlAPI server.

Sébastien.
