[BRLTTY] little off topic: alva delphi keys don't work

These settings are indeed what the driver is expecting.

>I've connected the cable to s1 port and the result is the same (the options

One general question comes to mind. Have you used the very same cable 
successfully before with the Delphi? If it's worked before then I don't know 
what might be wrong. If it's never worked before then it's possible that it's 
the wrong kind of cable.

There are two things that might be wrong with the cable. Please understand that 
these are just guesses as I'm not familiar with a Delphi. The first is that it 
might be a straight-through cable whereas the Delphi may require a null-modem 
cable, or vice versa. The second is that it may be a five-wire cable wehreas 
the Delphi may require a nine-wire cable.

Another possibility, of course, is that you need to reseat either or both ends 
of the cable within their respective ports.

Yet another possibility is that you're specifying the wrong port when invoking 
brltty.

Perhaps you're not specifying any port at all and expecting brltty to find it. 
If so, that won't work as brltty assumes USB by default. You need to use either 
the -d command line option or the braille-device directive in brltty.conf to 
tell brltty which serial port your Delphi is connected to.
