- *
- * $Log: l3_1TR6.c,v $
- * Revision 1.7 1997/02/11 01:38:55 keil
- * Changed setup-interface (incoming and outgoing)
- *
- * Revision 1.6 1996/09/25 18:34:57 keil
- * missing states in 1TR6 Statemachine added
- *
- * Revision 1.5 1996/09/23 01:53:51 fritz
- * Bugfix: discard unknown frames (non-EDSS1 and non-1TR6).
- *
- * Revision 1.4 1996/06/06 14:22:28 fritz
- * Changed level of "non-digital call..." message, since
- * with audio support, this is quite normal.
- *
- * Revision 1.3 1996/04/30 21:54:42 isdn4dev
- * SPV, callback , remove some debugging code Karsten Keil
- *
- * Revision 1.2 1996/04/20 16:47:23 fritz
- * Changed statemachine to allow reject of an incoming call.
- * Report all incoming calls, not just those with Service = 7.
- * Misc. typos
- *
- * Revision 1.1 1996/04/13 10:25:16 fritz
