+ * CommandHandler for the PASV command. Handler logic:
+ * <ol>
+ * <li>If the user has not logged in, then reply with 530</li>
+ * <li>Otherwise, request the Session to switch to passive data connection mode. Return a reply code of 227,
+ * along with response text of the form: "<i>(h1,h2,h3,h4,p1,p2)</i>", where <i>h1..h4</i> are the
+ * 4 bytes of the 32-bit internet host address of the server, and <i>p1..p2</i> are the 2
+ * bytes of the 16-bit TCP port address of the data connection on the server to which
