No but this must be getty/stty and/or terminal definition related.

Look at output of:

[kloczek at test1 ~]$ infocmp -I | grep kbs
        is2=\E[!p\E[?3;4l\E[4l\E>, il1=\E[L, kb2=\EOE, kbs=\177,
                                                           ^^^^
[kloczek at test1 ~]$ stty -a | grep erase -w
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = M-^?; eol2 = M-^?;
                              ^^

and compare kbs terminfo definition (or termcap if used getty is linked 
with libtermcap) and erase sequence on stty output.
