Did svr2 have anything similar to modern behavior when handling the 
delete/backspace key where the character is deleted from the input and 
rubbed out? The default, like in v6/v7 for erase and kill is # and @. I 
can live with this, if I can't get it to do the rubout, because at least 
you can see the # in the input, but if I can figure out how to get it to 
rubout the last character, I'd map erase to DEL, which I believe to be 
^U (but since it's invisible, it's confusing when it doesn't rubout).

I use ASCII 'backspace' (^H) on my V6, and it 'sort of' works; it doesn't
erase the deleted character on the screen, but if one then types corrected
characters, they overlay the deleted ones, leaving the corrected input.  That
should work on everything later than V6.

The MIT PWB1 tty handler (link in a prior message) not only supported a 'kill
line' (we generally used '^U') which actually visibly deleted the old line
contents (on screen terminals, of course; on printing terminals you're
stuck), it also had suppport for '^R' (re-type line) and some other stuff.
