BELL [DUAL MODE]
NAME BELL - Make an audible sound on the speaker.
SYNTAX
bell [frequency duration]* [/NOD] OR
bell -F file OR
bell /H | /?
USAGE
Bell is used to play a tune of the given frequency and
duration on the speaker. It can be given multiple such
pairs on the command line or the pairs can be given in a
file. If the parameters are in a file, each pair must be
on a separate line. That is: do not write multiple
frequency duration pairs to the same line in the file.
Bell can be given a default frequency and duration with
environment variables BELLFREQ and BELLDUR. When bell is
started with parameters are given, it uses the values
given in these environment variables. If beither of these
values or both are missing, and bell is started without
parameters, it reads the from the standard input. This
can be forced also with the /NOD-option, when environemt
variables are set.
