   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.

  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.
