Yes, it's most permanently set in /etc/termcap or terminfo, but you can edit those if you want
vt100|vt100-am|dec vt100 (w/advanced video):\
:am:bs:ms:xn:xo:\
:co#80:it#8:li#24:vt#3:\
:@8=\EOM
O=\E[%dB:K1=\EOq:K2=\EOr:K3=\EOs:K4=\EOp:K5=\EOn:\
This system assume bs=^? for the vt100 terminal setting -- so
... etc
You change it at the command line with
stty erase ctl-v [backspace] (define it to be what you want no matter what)
or
tput kbs (make sure it's set correctly for the terminal type
Hope that helps
