There is very little to report regarding dealing with spurious break 
signals on BSD 4.1 Un*x.  The bulk of the suggestions were to set the
interrupt character to something other than <delete> but BSD treats break
the same as your interrupt character regardless of what the interrupt
character is so that is no help.

Other suggestions were to:
	nohup things 
	use emacs to control your shell and re-map characters
		(I assume this suffers from the above lack but I don't
		really know)
	modify the driver to treat break and interrupt separately
		(I like this the best and may give it a try)
	enable parity to try to filter out the bad characters
		(may help in some cases but break isn't a character in
		the strict sense so this doesn't work)
	switch to USG which already has the feature
		(this was accompanied by a modest amount of gloating)
	do something unpleasant to the Phone Company for putting the
	noise on the lines in the first place
		(has possibilities but then again I work for BTL)
