Two questions about programming for floppy drives:

1. How can you query the drive's MEDIA CHANGED status?  I know that there is
   a device driver function for this, but the DOS IOCTL call doesn't seem to
   provide a call for it.

2. Can you tell if the drive is ready (i.e., media inserted and door closed)?
   I know there is a DOS function call where you can detect "media ready" for
   a handle, but I'd like to check before I open a file on the diskette.  Can
   you get a handle for the device itself?
