/** RCS log of revisions to the C source code.
 *
 * \begin{verbatim}
 * $Log: apf9com.c,v $
 * Revision 1.15  2011/04/12 19:32:49  swift
 * Increased the wait period after the serial port was enabled...improved reliability of the RTS/CTS lines.
 *
 * Revision 1.14  2010/10/11 14:55:13  swift
 * Fixed a bug that caused byte-loss if Tx buffer not empty on shutdown.
 *
 * Revision 1.13  2010/03/14 15:24:55  swift
 * Added ibytes() primitive to return the number of bytes in the input queue.
 *
 * Revision 1.12  2008/07/14 17:06:13  swift
 * Increased the size of the IO buffers to facilitate Sbe41cp gateway mode.
 *
 * Revision 1.11  2007/06/08 02:16:56  swift
 * Fixed return values of some functions to report success.
 *
 * Revision 1.10  2007/04/24 01:43:05  swift
 * Added acknowledgement and funding attribution.
 *
 * Revision 1.9  2006/04/21 13:45:38  swift
 * Changed copyright attribute.
 *
 * Revision 1.8  2006/01/06 23:10:07  swift
 * Added rts(), cts(), dtr(), and dsr() primitives to the SerialPort interface.
 *
 * Revision 1.7  2005/06/14 18:57:19  swift
 * Modifications to initialize low-level UART hardware before VALID line is active.
 *
 * Revision 1.6  2005/01/06 00:50:42  swift
 * Fixed bugs in RTS/CTS control.
 *
 * Revision 1.5  2004/12/29 23:02:52  swift
 * Modified LogEntry() to use strings stored in the CODE segment.  This saves
 * lots of space in the DATA segment and significantly speeds code start-up.
 *
 * Revision 1.4  2004/07/14 22:49:28  swift
 * Modified SerialPort objects to be constant.
 *
 * Revision 1.3  2004/04/14 20:48:21  swift
 * Revision E of the APF9 made some hardware changes to earlier versions.  The
 * PSD935 was replaced by a PSD835 and the 20mA serial loop was changed to be a
 * real serial IO port.
 *
 * Revision 1.2  2003/11/20 18:59:35  swift
 * Added GNU Lesser General Public License to source file.
 *
 * Revision 1.1  2003/09/19 23:41:43  swift
