  * Common module for AVM B1 cards.
  * 
  * (c) Copyright 1999 by Carsten Paeth (calle@calle.in-berlin.de)
  * 
  * $Log: b1.c,v $
+ * Revision 1.12  1999/11/05 16:38:01  calle
+ * Cleanups before kernel 2.4:
+ * - Changed all messages to use card->name or driver->name instead of
+ *   constant string.
+ * - Moved some data from struct avmcard into new struct avmctrl_info.
+ *   Changed all lowlevel capi driver to match the new structur.
+ *
+ * Revision 1.11  1999/10/11 22:04:12  keil
+ * COMPAT_NEED_UACCESS (no include in isdn_compat.h)
+ *
+ * Revision 1.10  1999/09/15 08:16:03  calle
+ * Implementation of 64Bit extention complete.
+ *
+ * Revision 1.9  1999/09/07 09:02:53  calle
+ * SETDATA removed. Now inside the kernel the datapart of DATA_B3_REQ and
+ * DATA_B3_IND is always directly after the CAPI message. The "Data" member
+ * ist never used inside the kernel.
+ *
  * Revision 1.8  1999/08/22 20:26:22  calle
  * backported changes from kernel 2.3.14:
  * - several #include "config.h" gone, others come.
