[BRLTTY] BRLTTY and Raspberry PI

[kperry at blinksoft.com]

I looked at all  the branches on github.  I don't see a dev or a 6.5.  Is
there a way to get an early look at the new version? So far I have not been
able to get the orbits to work in emulation mode so I guess I have to wait
on the new release.

I will also mention when I tried to run with the run script it could not
find some stuf fand still seemed to want me to install it before running
which maybe just my lack of knowledge with brltty.

>BRLTTY seems to require the PcSPKR module which is the PC speaker module.
Raspberry PI does not have that module compiled with the kernel so you can't
modprobe it. Is there steps to get BRLTTY working with Raspberry PI command
line?

No, brltty doesn't require the pcspkr kernel module. The default for the
alert tunes is to use it, but brltty continues along just fine without it -
it's just that, you won't hear any of the alert tunes.

Brltty, as it should, logs the fact that it can't use the pcspkr kernel
odule, but that's only a warning. This is how brltty works. If there's a
feature that it wants to use but can't, then it continues without that
feature as best it can.

Please take care that you don't install your own build over top of the
raspbian-supplied version. In other words, please configure your own brltty
in a way that installs it to some other location (e.g. usr/local/).

Also, you can run brltty right out of your build tree. To do this, you use
the run-brltty script. Doing it this way means that you don't need to
install it.

>I don't see any options in the configure script to do something else than
PCSPKR for a linux build.

Because that setting isn't done via configure. When brltty is running, you
go into its Preferences Menu, and then into its Event Alrts submenu. In
there, you can change the Tune Device from Beeper to PCM (which means your
sound card). Then you'll hear the alert tunes out of your speakers.

>I am also not sure if BRLTTY is running after it errors with no PCSPKR 
>or not

As mentioned above, it isn't an error - it's just a warning. If you'd like
to be sure that brltty is running, check for it with the ps command. The
quickest way (to me) is to do: pgrep -x brltty

Note that 6.4 didn't yet contain proper support for the Orbit Reader 40.
You'll need the development code for that. It'll be in 6.5, which I expect
to be releasing in a couple of weeks.
