# 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 --configuration-file= [-f] 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
# before the keyword, as well as before and after the operand. Keyword
# processing isn't case sensitive. Examples of valid entries are:
#
# Braille-Driver pm # Papenmeier braille displays.
# braille-device serial:ttyS0 # The first serial device.
# SPEECH-DRIVER fv # The Festival Text to Speech System.
# The default settings given within the following descriptions assume no
# special build options (see "./configure --help" in the top-level
# directory of the source tree.

# 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 --braille-device= [-d] option)
#braille-device serial:ttyS0 # 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: # First paired Bluetooth device matching braille driver.
#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, you needs to identify the
# virtual serial device which the kernel has created for the adapter, i.e. to
# something like serial:ttyUSB0 or ttyACM0 (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 --release-device [-r] 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.
