[BRLTTY] Brltty woes on Centos 7

[Keith Wessel]

Alright, I've made a much simpler brltty.service to try and simplify things,
and I'm getting this down to a console error. I've changed my system to only
boot to runlevel 3 to get Gnome out of the mix. But, when brltty starts at
boot, it still reports "screen not in text mode" on the braille display. The
journalctl output from brltty.service tells me that brltty is reporting:
control[console] error 5: Input/output error.

Is this a funky permissions issue with system not allowing console access
for some reason? Oddly, once I'm logged in, I can stop and restart brltty
either using the executable directly or my system service, and it comes up
fine. I'm blaming that "after I've logged in" part, and that's why I'm
suspecting system permissions.

Any thoughts?

Thanks,
Keith

Hi, Dave,

Sorry, I would have gone into detail about the spec file before, but since
the recommendation was to build from the tar, I wasn't sure if anyone cared.
I shouldn't have assumed that.

I had to disable the java bindings in the configure line as you instructed.
I had to add a: Provides: config(brltty) line because rpm complained when I
didn't that config(brltty) = 5.4.1 couldn't be satisfied. I also had to
change all references to brlapi-python to instead be to python-brlapi to
make dependencies happy for Orca. While I was at it, I did the same for
brlapi-ocaml and brlapi-tcl just for the heck of it. I'm happy to send along
an updated spec file if you like.

There is a system file in the RPM, but so far, it's not working for me. Mind
you, neither is my own. Brltty starts then stops; journalctl is reporting
some garbage chars from the braille display communications. I'm suspecting
the communications channel is out of syn for some reason. Still tinkering. I
don't have this problem at home, but I also don't have the same system
hardware at home. Same braille display model, but everything in the computer
is different. The one at home doesn't even have on-board serial ports; I'm
using a SIIG Cyberserial PCI add-on card. Ah, good ol' RS-232 fun.

I'll follow up when I get to the bottom of this.

Keith

>I made a couple of modifications to the brltty.spec file from the srpm 

What were those changes?

there should be systemd units in the rpm.
