Set USB Key Clicks Application
SetUsbKeyClick
is
a
Windows
application
for
the
Desktop
O/S
versions
(Windows
98se,
Windows
2000)
that
uses
the
NCRUsbKeyboardCtl
control
to
set
keyclick
tone
parameters.
The
application
operates
as
a
memory
‐
resident
background
process
for
a
duration
that
may
be
specified
on
the
command
line.
If
no
duration
is
specified,
the
application
remains
resident
until
terminated
by
user
action.
While
resident,
the
application
receives
device
‐
attachment
notifications
for
HID
devices,
and
when
these
are
received,
invokes
the
NCRUsbKeyboardCtl
control
to
set
key
click
tone
parameters.
