I don't doubt it in the least, because I've *used* SunOS, and it *does*
default to DEL.

BSD defaults to DEL, because the conventions *it* uses by default are
those of DEC operating systems (except for the end-of-file character;
DEC OS's tend to use ^Z, as I remember, but BSD uses the UNIX ^D
convention for end-of-file, and uses ^Z for "suspend").  A number of the
OS's the original poster listed as using DEL for the "erase" character
inherited that convention from BSD.
