007/**
008 * Handle XML persistance of layout connections by persistening the
009 * SerialDriverAdapter (and connections). Note this is named as the XML version
010 * of a ConnectionConfig object, but it's actually persisting the
011 * SerialDriverAdapter.
012 * <p>
013 * This class is invoked from jmrix.JmrixConfigPaneXml on write, as that class
014 * is the one actually registered. Reads are brought here directly via the class
015 * attribute in the XML.
