These two cases, and buggy programs, are the only problems you cannot fix
with simple keymapping and a tweak to the xterm terminfo.

You can fix these by having a wrapper that runs broken programs, or connections 
to broken systems for you, which translates what you type into what the other 
end wants to see:

--< bsdelfix >--
#!/usr/bin/expect

eval spawn -noecho $argv

interact {
 \177        {send "\008"}
 "\033\[3~"  {send "\177"}
}
-----------

which you run like this:

  bsdelfix telnet brokenhost

or

  bsdelfix brokeneditor

end of problem.

Cheers, Phil.

P.S. don't you just love expect ? :-)
