It sounds like this is not a bug, but an intended change in behavior,
which somehow clashes with your xterm/Emacs customizations which were
optimized for the pre-v21 behavior.

My guess is that your xterm and/or your shell startup files on the
Solaris side set up the Backspace key to produce the [deletechar]
escape sequence.  Try using "C-h l" (that's a letter ell, not a digit
one) to see what does Emacs receive when you press that key.

Also, the new function normal-erase-is-backspace-mode might help you
set this straight.  The description of the related issues in the
manual, in the sections "Deletion" and "If <DEL> Fails to Delete",
should also prove useful.

If all of the above does not help to resolve the problem, or at least
understand why exactly the behavior changed since Emacs 20.7, please
report the details that you discovered here.
