There is a statement in the /etc/bashrc file:
stty erase `tput kbs`

It appears twice in the file:
stty erase `tput kbs`

When I run tput kbs, nothing is displayed.  Below is a snippet from the
bashrc file with the conditionals.

# are we an interactive shell?
if [ "$PS1" ]; then
    if [ -x /usr/bin/tput ]; then
      if [ "x`tput kbs`" != "x" ]; then # We can't do this with "dumb"
terminal
        stty erase `tput kbs`
      elif [ -x /usr/bin/wc ]; then
        if [ "`tput kbs|wc -c `" -gt 0 ]; then # We can't do this with
"dumb" terminal
          stty erase `tput kbs`
        fi
      fi
    fi
