/*
<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.
