 * Implement mag-switch shut-down feature and 20mA squawk.
 *
 * Revision 1.9  2007/05/08 18:10:39  swift
 * Added attribution just below the copyright in the main comment section.
 *
 * Revision 1.8  2006/10/13 18:53:09  swift
 * Add conditioning to logstream.
 *
 * Revision 1.7  2006/08/17 21:17:59  swift
 * Modifications to allow better logging control.

 * Changed copyright attribute.
 *
 * Revision 1.5  2004/12/29 23:11:26  swift
