2 * 16 Feb 93 Julian Elischer (julian@dialix.oz.au)
8 <1> Fixed a conflict with ioctl usage. There were two different
9 functions using code #25. Made file formatting consistent.
10 Added two new ioctl codes: door closing and audio pitch playback.
11 Added a STEREO union called STEREO.
12 5-Mar-95 Frank Durda IV bsdmail@nemesis.lonestar.org
14 <2> Added a new ioctl that allows you to find out what capabilities
15 a drive has and what commands it will accept. This allows a
16 user application to only offer controls (buttons, sliders, etc)
17 for functions that drive can actually do. Things it can't do
18 can disappear or be greyed-out (like some other system).
19 If the driver doesn't respond to this call, well, handle it the
20 way you used to do it.
