bellctrl
is used to set various preference options of
the opm bell.
The options are as follows:
-b
- The b option controls bell volume, pitch and duration. This option accepts
up to three numerical parameters, a preceding dash(-), or an 'on/off'
flag. If no parameters are given, or the 'on' flag is used, the system
defaults will be used. If the dash or 'off' are given, the bell will be
turned off. If only one numerical parameter is given, the bell volume will
be set to that value, as a percentage of its maximum. Likewise, the second
numerical parameter specifies the bell pitch, in hertz, and the third
numerical parameter specifies the duration in milliseconds.
- v default
- The default argument cause the voice parameter to be
reset to the system default.
-v
voicefile
- The
-v
option sets the voice parameter to given
voice parameter file ( voicefile).
