	This is an odd idea, and I have no clue if it'll actually work,
but...

	Well, looking at the manual and playing with it a bit indicates
that it won't, but here's the idea anyway.  Look for the device in the
/dev directory and use mknod to make another with a different minor
number and see what happens.  :-)

	Why ever aren't all the devices you have in the /dev directory
somewhere?  I thought that one of the tenets of the UNIX design
philosophy is that everything is a file.

Have fun (if at all possible),
