+ * $Log$
+ * Revision 1.1 2008-01-22 09:27:13 groke6
+ * Added can4linux driver support.
+ *
+ * Revision 1.1 2004/08/12 10:14:31 jschoew
+ * add can4linux examples
+ *
+ * Revision 1.5 2004/05/14 10:02:54 oe
+ * - started supporting CPC-Card
+ * - version number in can4linux.h available
+ * - only one structure type for Config_par_t Command_par_t
+ * - new ioctl command CMD_CLEARBUFFERS
+ *
+ * Revision 1.4 2003/08/27 17:49:04 oe
+ * - New CanStatusPar structure
+ *
+ * Revision 1.3 2002/08/20 05:57:22 oe
+ * - new write() handling, now not ovrwriting buffer content if buffer fill
+ * - ioctl() get status returns buffer information
+ *
+ * Revision 1.2 2002/08/08 17:50:46 oe
+ * - MSG_ERR_MASK extended
+ *
+ * Revision 1.1 2002/01/10 19:13:19 oe
+ * - application header file changed name can.h -> can4linux.h
+ *
+ * Revision 1.2 2001/09/14 14:58:09 oe
+ * first free release
+ *
+ * Revision 1.1.1.1 2001/06/11 18:30:54 oe
+ * minimal version can4linux embedded, compile time Konfigurierbar
