It worked, huge thanks Dave and Samuel!

And now I have a log ~/log_xbrlapi

Does that implies that the braille device should be connected before
booting? Or will this work if the device is connected after the daemon
has started?

Also, I had first commented all lines under:
Application Programming Interface Parameters in /etc/brltty.conf
and I assume that this is not safe.

This leads to another question.

Currently I include this code snippet in brltty's post-install script:
---
if [ ! -f etc/brlapi.key ]; then
	chmod 755 usr/sbin/brltty-genkey
	usr/sbin/brltty-genkey etc/brlapi.key
	usr/bin/chgrp braille etc/brlapi.key
	chmod 640 etc/brlapi.key
fi
---
I assume that this fits the setting below in /etc/brtty.conf:
api-parameters Auth=group:braille

If, say, I am more lenient and allow all local connections like this:
api-parameters Host=:0

Then could I have root:root own /etc/brlapi.key and make it 644?

Is the increased security allowing only members of the braille group
worthwile? Bear in mind that I am searching a convenient default
setting for Slint, that the admin could of course change after
installation.

I have a completely different question about the coexistence of espeakup
and orca, but to make the discussions easier to follow will ask it in
another thread.
