What do you call function keys? Are you on HP term?

If you mean backspace etc not working then its in your .profile:

# Set up the terminal:
      if [ ! "$DT" ]; then
        if [ "$TERM" = "" ]
        then
                eval ` tset -s -Q -m ':?hp' `
        else
                eval ` tset -s -Q `
        fi
        stty erase "^H" kill "^U" intr "^C" eof "^D"
        stty hupcl ixon ixoff cs8 -istrip -parenb
        tabs
     fi
