We've returned from a longish out of town trip, and I'm now retrying to install brltty on a new machine. The previous posting was as follows:

I have read through the documentation on preferences and set some of them in the config file. Is there a way to reverse the functions of the two rocker bars on the Power Braille 80? I haven't been able to find a configuration entry that controls that preference. Thanks! -------------- next part -------------- An HTML attachment was scrubbed...

There are system-wide defaults (that are defined in /etc/ brltty .conf), and there are user-specific settings (that are stored in /var/lib/ brltty / brltty .prefs). It's the latter - the user-specific settings - that are commonly known as preferences because they can be (and really should be) modified from the braille device itself via brltty 's Preferences Menu. There's a way to do it from brltty .conf - with the override-preference directive - but that should only be done when absolutely necessary because it undoes changes made within the menu. >Is there a way to reverse the functions of the two rocker bars on the Power >Braille 80?

Assuming a normal install, you should be able to find it at: /etc/ brltty /Input/ts/pb80.ktb -- I believe the Bible to be the very Word of God: http://Mielke.cc/bible/ Dave Mielke | 2213 Fox Crescent | WebHome: http://Mielke.cc/ EMail: [email protected] | Ottawa, Ontario | Twitter: @Dave_Mielke Phone: +1 613 726 0014 | Canada K2A 1H7 | ------------------------------ Subject: Digest Footer _______________________________________________ This is a message digest of the BRLTTY mailing list.

The operating system is Debian Linux 9.4. 1.) I opened /etc/brltty/Input/ts/pb80.ktb with nano, and found five lines: title Power Braille 80 assign routingRight1 81 assign routingRight2 82 assign routingRight3 79 include pb_large.kti Neither I nor my friend understands what these entries refer to, and none mentions a rocker switch. What parameters should I change to reverse the rocker bar settings? Since I'm seven hours from his home in Chicago at the moment and could not connect a PB80 to test or access the preferences file to see if that preference was there, I tried looking in /var/lib/brltty, but did not find brltty.prefs at all. 2.) Also, to insure that the PB80 display starts at boot, I added the lines braille-driver ts braille-device serial:ttyS0 to /etc/brltty.conf. Then, per another entry in the documentation, I edited /etc/default/brltty as follows: ARGUMENTS="-q -b ts -d /dev/ttyS0" Am I correct in assuming that these changes will automatically start brltty at boot? Thanks again for all your support.
