/*
<1> Fixed a conflict with ioctl usage. There were two different
functions using code #25. Made file formatting consistent.
Added two new ioctl codes: door closing and audio pitch playback.
Added a STEREO union called STEREO.
5-Mar-95 Frank Durda IV bsdmail@nemesis.lonestar.org
<2> Added a new ioctl that allows you to find out what capabilities
a drive has and what commands it will accept. This allows a
user application to only offer controls (buttons, sliders, etc)
for functions that drive can actually do. Things it can't do
can disappear or be greyed-out (like some other system).
If the driver doesn't respond to this call, well, handle it the
way you used to do it.
