	No.  For some reason, when I use Gnome or KDE, the system speaker
	goes dead.  Hitting ESC in nvi does not work, and because I only
	watch the keyboard and not te screen, I rely on the audio
	feedback.   (I used to use Suns at work and turned on "click" to
	make certain that I actually hit a key.   It drove my co-workers
	batty, but that was just until we moved into offices!)  Nutshell,
	I will either buy a fancyy clicky keyboard or write a CLICK
	Driver.    Meanehile, unless I set Konsole to ring the WAV belll,
	no *ding*.

	Zounds! same here.  I'm working in my old tao running ctwm, and
	yup, same thing with vi/nvi.  vim does erase.  '\b' ' ' '\b'
	was how I coded it tone time.  The thing I don't like about vim
	is that I foul up with 'u' undo's.  Is there some magic to makr
	vim behave more like the old vi?  Hmph!

	Well, in the dfault mode with keyboard == Xterm 4, it backs up
	and erases in command-ln mode, but both vi and vi still run into
	the "^?" characters.  Even given  you stty cms.  However, if I
	set the keyboard to "freebsd", the first in the list, it erases 
	wit bakspace.   In vi, tho, as you noted above, it does not
	blank the character; in vim it both backs up then forward to
	blank, then backwards.

	(Be nice to understand what's going on without days of digging
	into the code!)
