hello mr Jakub.
i think you have the same baum display as one of mine.
I would like to try to help you, and for that I need to learn a couple 
of things.
1. Are you using the original COM cable that came with the display from 
the factory?
it looks like a flat wire with two female plugs on the ends.

it is very important to use the original wire as its pinout differs from 
the usual internal pinout of the rs232 connector. several of these wires 
were made for me.

2. have you checked the two connection pins? they are equivalent, but I 
managed to burn one on one of my displays.

you should also be careful with your com to usb converter.
for me, one of these broke after a week of use.
for a start, look either in the kernel logs, or in / dev /, or better 
both whether the adapter is detected when connected.
and specify the path to its device in brltty.conf. most likely it will 
be / dev / ttys0-usb
