 *
 * $Log: SIN.c,v $
 * Revision 1.9  2003/07/24 04:48:09  reinelt
 * 'soft clear' needed for virtual rows
 *
 * Revision 1.8  2003/02/22 07:53:10  reinelt
 * cfg_get(key,defval)
 *
 * Revision 1.7  2001/04/27 05:04:57  reinelt
 *
 * replaced OPEN_MAX with sysconf()
 * replaced mktemp() with mkstemp()
 * unlock serial port if open() fails
 *
 * Revision 1.6  2001/02/13 09:00:13  reinelt
 *
 * prepared framework for GPO's (general purpose outputs)
 *
 * Revision 1.5  2000/12/07 20:47:54  reinelt
 *
 * first try for SIN bars
 *
 * Revision 1.4  2000/12/01 20:42:37  reinelt
 *
 * added debugging of SIN driver output, probably found the positioning bug (format %02x instead of %2x)
 *
 * Revision 1.3  2000/12/01 07:20:26  reinelt
 *
 * modified text positioning: row starts with 0, column is hexadecimal
 *
 * Revision 1.2  2000/11/28 17:27:19  reinelt
 *
 * changed decimal values for screen, row, column to ascii values (shame on you!)
 *
 * Revision 1.1  2000/11/28 16:46:11  reinelt
 *
 * first try to support display of SIN router
