    bottom margin, you can now create a completely separate sub-window.
    
    This command replaces CSI s to save the cursor position... since this
    non-standard extension is very widely used, set left/right margin only
    works when mode 69 is enabled using CSI ? 69 h.  The margins are retained
    when CSI ? 69 l is sent, only the command to adjust them is disabled.
