The pen status is given by the position of the pen-lift servo output, which can be controlled with the <code><a href="#SP">SP</a></code> command and can be read with the <code><a href="#QP">QP</a></code> query. Note that this is the <i>commanded state</i> of the pen, and that it does physically take time to lift from or lower to the page.
