/*
 * ListScsi.m
 *    - This, and the main routine it calls (do_inquiryall), were
 *	written by Garance Alistair Drosehn/Mar 1994.  Note that
 *	do_inquiryall may not be safe to call at all times.  For the
 *	most part this works fine for me, but occasionally it will
 *	totally lock up my machine for a minute or so.  Thus I do
 *	not recommend it's use (until someone can fix do_inquiryall).
