The error "permission denied" means that the device exists but that brltty
isn't allowed to access it. The most likely cause for this is that you're
invoking brltty as a normal user rather than as root.

>I typed brltty serial:ttyS0 and even tried just brltty but still get the

You need to specify the device via the -d option. It's not just a positional
parameter. Specify it lke this: -d serial:ttyS0
