[comp.sys.mac] Has anyone driver stepper motors from a Mac?

I am trying to drive a pan/tilt mechanism from a MacII.  Has anyone
done this?  How about just driving a stepper motor from a Mac?  The
RS-422 causes some complexities since most off-the-shelf stuff is
RS-232. I also understand that the Apple RS-422 is non-standard. In
what way, though?  Any help is helpful.
