If an environment variable named NOMIDI
is defined when
the plugin is loaded, MIDI will be disabled and APING
will not make any sounds. (The contents of the variable don’t matter,
so long as it contains something.) Setting this variable allows you to use
the plugin on systems which don’t support MIDI:
set nomidi=1
plugin /l c:\bin\tcmd\test\aping.dll
Setting the NoMidi
registry variable
to a nonzero value does the same thing.
