013 * Handle XML persistence of layout connections by persisting the
014 * SerialDriverAdapter (and connections).
015 * <p>
016 * Note this is named as the XML version of a ConnectionConfig object,
017 * but it's actually persisting the SerialDriverAdapter.
018 * <p>
019 * This class is invoked from jmrix.JmrixConfigPaneXml on write, as that class
020 * is the one actually registered. Reads are brought here directly via the class
021 * attribute in the XML.
