Connection configuration variables allow you connect to Speech Dispatcher or BRLTTY running on a remote host or a non-default port and to specify other TCP connection parameters.
Speech Dispatcher connection options:
speechd-connection-method
¶Connection method to Speech Dispatcher. Possible values are symbols
unix-socket
for Unix domain sockets and inet-socket
for
Internet sockets on a given host and port.
speechd-host
¶Name of the host running Speech Dispatcher to connect to, given as a
string. Default is either the contents of the shell variable
SPEECHD_HOST
variable if set, or "localhost"
. Value of
this variable matters only when Internet sockets are used for
communication with Speech Dispatcher.
speechd-port
¶Port number to connect to. Default is either the contents of the
shell variable SPEECHD_PORT
if set, or the default Speech
Dispatcher port. Value of this variable matters only when Internet
sockets are used for communication with Speech Dispatcher.
speechd-autospawn
¶If non-nil
, Emacs will attempt to automatically start Speech
Dispatcher. This means that if speechd-el gets a speech request and
the Speech Dispatcher server is not running already, speechd-el will
launch it.
speechd-timeout
¶Maximum number of seconds to wait for a Speech Dispatcher answer. If it is exceeded, speechd-el closes the connection. Normally, Speech Dispatcher should answer protocol commands immediately, but if you talk to a Speech Dispatcher in a strange way through a lagging network, you may want to increase the limit.
BRLTTY connection options:
brltty-default-host
¶Name of the host running BRLTTY to connect to, given as a string.
Default is "localhost"
.
brltty-default-port
¶Port number to connect to. It can be either a single number or a list of numbers; in the latter case the given port numbers are attempted in the order they are given until Emacs connects to something. Default is the list of the standard BrlAPI ports.
brltty-authentication-file
¶File containing the BrlAPI authentication key. It is important to set
the variable properly, otherwise the connection to BRLTTY gets
rejected. Default is "/etc/brlapi.key"
.
brltty-coding
¶Coding in which texts should be sent to BRLTTY. Default is
iso-8859-1
; if you use non-Western language, you may need to
change it to display its characters correctly on the Braille display.
brltty-tty
¶Number of the Linux console on which speechd-el runs. If this value
is not set correctly, speechd-el may not interact well with other
applications communicating with BRLTTY. speechd-el tries to find the
correct value itself, if this doesn’t work, set this variable properly
or set the CONTROLVT
environment variable.
brltty-timeout
¶Maximum number of seconds to wait for a BRLTTY answer. If it is exceeded, speechd-el closes the connection. Normally, BRLTTY should answer protocol commands immediately, but if you talk to BrlAPI in a strange way through a lagging network, you may want to increase the limit.
