 * Fixed a bug that cleared the wrong bit on the wrong port.
 *
 * Revision 1.17  2010/10/11 14:55:13  swift
 * Fixed a bug that caused byte-loss if Tx buffer not empty on shutdown.
 *
 * Revision 1.16  2010/03/14 15:24:55  swift
 * Added ibytes() primitive to return the number of bytes in the input queue.
 *
 * Revision 1.15  2007/04/24 01:43:05  swift
 * Added acknowledgement and funding attribution.
 *
 * Revision 1.14  2006/04/21 13:45:38  swift
 * Changed copyright attribute.
 *
 * Revision 1.13  2006/03/24 23:37:55  swift
 * Eliminated conditional 3s pause in favor of unconditional 3 sec pause after
 * enable.
 *
 * Revision 1.12  2006/03/24 23:05:29  swift
 * Eliminated firmware kludge to fix nonresponsive LBT9522a modems.  This
 * problem was solved correctly with a hardware fix.
 *
 * Revision 1.11  2006/03/15 15:59:57  swift

 * Implemented a kludge to fix nonresponsive LBT9522a modems.  After a hardware
 * fix is implemented and tested, this kludge should be eliminated.
 *
 * Revision 1.9  2006/01/16 18:34:31  swift
 * Fixed problems with implementation of na() and na_().
 *
 * Revision 1.8  2006/01/06 23:08:54  swift
 * Added dtr(), and dsr() primitives to the SerialPort interface for the modem port.
 *
 * Revision 1.7  2005/07/07 19:45:04  swift
 * Assert the DTR line when the iridum module is powered up.
 *
 * Revision 1.6  2005/06/14 18:57:19  swift
 * Modifications to initialize low-level UART hardware before VALID line is active.
 *
 * Revision 1.5  2005/02/22 21:56:51  swift
 * Clean-up and fix-up of GPS serial port code.
 *
 * Revision 1.4  2005/01/15 00:52:03  swift
 * Added a time delay of 500ms to GpsEnable() to allow time for the GPS to boot
 * up.
