Looking at the source (2.1.6), It's very interesting, but I've found (on 2.1.5), that the newer cdcontrol cannot work, but the original cdplay works with it. > well, yeah - the ioctls aren't implemented.

Maybe, somebody has to sit down, and rewrite the mcd/matcd/scd drivers, to use the same interface as the ATAPI or the SCSI version of the CD-driver. > What's the legality / possibility of figuring out what's going on from > a disassembled version of e.g. the DOS driver? ????. If you can do it, try to search the locking mechanism, which isn't implemented, too. But there are so many DOS-commands, which can do it with my CDU 33A (connected to a SB Vibra16). And of course, it would be nice, as FreeBSD is crashing if my two-years-old son pushes the eject button with a mounted CD in it. Gabor
