 *
 * Revision 1.9  2001/05/27 07:19:28  reinelt
 *
 * fixed a warning in pixmap.c
 * temporarily fixed a bug in isdn.c (ISDN_MAX_CHANNELS is no longer defined?)

 *
 * Revision 1.8  2001/04/27 05:04:57  reinelt
 *

 * replaced mktemp() with mkstemp()
 * unlock serial port if open() fails
 *
 * Revision 1.7  2001/03/17 11:44:10  ltoetsch
 * allow more than 1 BAR_T
 *
 * Revision 1.6  2001/03/16 16:40:17  ltoetsch

 *
 * memory leak in Raster_flush closed
 * driver family logic changed
 *
 * Revision 1.3  2000/03/24 11:36:56  reinelt
 *
 * new syntax for raster configuration
 * changed XRES and YRES to be configurable
 * PPM driver works nice
 *
 * Revision 1.2  2000/03/23 07:24:48  reinelt
 *
 * PPM driver up and running (but slow!)
 *
 * Revision 1.1  2000/03/22 15:36:21  reinelt
