Yes, I did some digging and found the VT220 backspace key *does* produce 
a DEL character, but that character would be interpreted as a backspace. 
  The Delete key produced an escape sequence that performed a delete 
function.  Can they make it any more complicated?

Yeah, and lehs seems to be unhappy with it.  :(
