I will have to assess the consequences. Patrick Volkerding wrote it, I 
have to first understand why before making such a change in the main 
startup script.

But there was no issue with brltty-6.1

Really? Next questions from 3 1/2 yo grandson would probably be:
What is a good app?
And why are these designed this way these days?
But I'm Didier not Lucas, so feel free to not answer :-)

I'm not paid either to maintain Slint, but that doesn't bother me at all.
System integration is my hobby, and that it can help a few is rewarding 
enough.

Attached. The root partition being still mounted ro I just wrote:

mount -rw UUID="3C8C-1441" /mnt/tmp #This is on an US stick
...
/bin/brltty -b tt -d /dev/tty3  -ldebug,usb,async -L/mnt/tmp/brlttylog1

the ",usb" is pointless (no physical braille display) but doesn't hurt, I
assume.

killal brltty just stop the output on /dev/tty3 but doesn't kill the daemon.
I didn't check if the log goes beyond the SIGTERM, if necessary I will.

Best regards,
Didier
