Hi guys!
I'm Jakub and new user of BRLTTY.
I've known about the existence of BRLTTY since ever, as I'm Linux user
since 1994. I've finished my master in media informatics in Berlin 2y
ago and during my studies, I've came across an exhibition in the
glorious Museum für Kommunikation about braille script and blindness in
general. I had the opportunity to write my name (or anything) on a
braille typewriter on paper and then read it with my finger. It was a
mind opening experience, since I've never before read anything with my
touch senses. Since then, I've been chasing used braille displays, which
would work explicitly with BRLTTY.
I came across a Baum display of the older type, but was reassured, that
it would work with a usb/rs-232 adapter. It's a pity, but it doesn't
work neither way. I've tried it on an older computer with current,
up-to-date XUBUNTU for direct RS-232 and later with an USB/RS-232 cable
on a newer computer, also with XUBUNTU. When turning on and off, it
displays words like "charge ready" or "time" and the current time
changing every second.
There's not much that You can do wrong during the configuration, hence
after a few hours, I'm "at the end of my latin". Please help. My goal is
to learn how to use it and to write a small communication and media
suite explicitly for BRLTTY and the users. I've attached my current
config, the log file which was produced by that config and a photo of
the braille display. The braille display is 40 chars wide, all black,
with one silver rectangle on the left with capital letters VARIO and
another on the right with the word BAUM. It has two connectors, one on
the backside on the left and one on the left side, next to the power
connector. With a special cable, which has RS-232 on the other end, I
can connect it to a PC. I hope, that it is in fact the Vario 40.
Background: I remember BBS times, where I knew a lot of blind users
(also from real user meetings), since they were using MS-DOS with
braille displays. At that time (around 1994), I was occupied with all
cyberspace related stuff, and was looking forward to the future, were I
hoped to witness real cyberspace myself. After some decades, it occured
to me, that the cyberspace I was waiting for, was right in front of me
all the time, since text mode internet of the early 1990s (telnet, lynx,
bbs) wasn't bloated with anything. It was pure information space, that
happened in our minds (everybody's individual imagination) and through
the connections between us, the users and the machines.
I want to add my piece to the available software and hopefully, I'll
make the first step and get a braille display up and running.
Thanks so much for Your precious attention,
Jakub

# This is a configuration file template for the BRLTTY application.
# Uncomment those entries which apply to your personal needs and system
# requirements.
# BRLTTY expects to find its configuration file in "/etc/brltty.conf"
# (can be overridden with the -f [--configuration-file=] option).
# If it doesn't exist, then BRLTTY silently continues but may require
# that certain command line options be explicitly supplied.
# Blank lines are ignored. The character '#', anywhere on a line,
# initiates a comment; all characters from it to the end of that line
# are ignored.
# Each configuration entry consists of a keyword followed by its operand.
# An arbitrary amount of white space, (blanks and/or tabs), may occur

# The braille-device directive specifies the device to which the braille
# display is connected. The generic syntax is type:device. The device
# type is optional, and, for backward compatibility, defaults to serial.
# The following devices are supported (brackets indicate optionality):
# serial:path (relative paths are anchored at "/dev")
# usb:[serial-number]
# bluetooth:address
# If not specified, "usb:,bluetooth:" will be used.
# If more than one device, separated by commas, is specified,
# then each of them will be probed in turn.
# (can be overridden with the -d [--braille-device=] option)
braille-device ttyUSB0 # First serial device.
#braille-device usb: # First USB device matching braille driver.
#braille-device usb:nnnnn # Specific USB device by serial number.
#braille-device bluetooth:xx:xx:xx:xx:xx:xx # Specific bluetooth device by address.
#
# NOTE: If the device is connected via a serial-to-USB adapter then setting
# braille-device to usb: will not work. In this case it needs to identify the
# virtual serial device which the kernel has created for the adapter, i.e. to
# something like serial:ttyUSB0 (see the kernel messages on device plug to get
# the actual device name).
# The release-device directive specifies whether or not the device to which the
# braille display is connected is to be released when the current screen or
# window can't be read by BRLTTY. If not specified, "on" will be used on Windows
# platforms and "off" will be used on all other platforms.
# (can be overridden with the -r [--release-device] option)
#release-device on # Release the device.
#release-device off # Don't release the device.
# The text-table directive specifies which text table to use. Relative paths
# are anchored at "/etc/brltty/Text". If not specified, locale-based
# autoselection with fallback to "en-nabcc" will be performed.
# (can be overridden with the -t [--text-table=] option)
