I just looked, and did not find this anywhere.
Anyway, what are the permissions on your brlapi-key file?

Gnopernicus does not touch /dev/ttyS0 at all when used with
BRLTTY.  It opens a TCP connection to the localhost by default,
and does all communication via that socket.
So if you are running gnopernicus as some user other than root,
you should ensure that this user can read the brlapi-key file.

Is there no other output?  Possibly above the first line you quoted?
I am wondering, since there is no indication which error happened.
