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

Hi,
I solved the problem, and I write to someone that have it in the future.
When we enter the display's preferences -> setup -> ser -> ser2 there are
two options here: alva and non-alva.
If I press non-alva, it presents me the screen to choose serial port
parameters. If I press alva, it presents me the string "alva devices" and is
a leaf option. It seems alva delphi works in two modes: alva and non-alva.
In alva mode it works correctly; in non-alva it let me choose the serial
port options. Even if I choose the correct options in non-alva mode, the
routing and navigation keys don't work, I don't know why. I choose the alva
mode and exited preferences. It works again.
Thanks.
Best regards,
Sérgio Neves

These settings are indeed what the driver is expecting.

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.
