  * $Log: queue.c,v $
- * Revision 1.4  1995-10-17 12:18:59  adam
+ * Revision 1.13  2003-03-05 21:21:42  adam
+ * APDU log. default largeSetLowerBound changed from 2 to 1
+ *
+ * Revision 1.12  1999/04/20 10:01:46  adam
+ * Modified calls to ODR encoders/decoders (name argument).
+ *
+ * Revision 1.11  1996/07/03 13:31:14  adam
+ * The xmalloc/xfree functions from YAZ are used to manage memory.
+ *
+ * Revision 1.10  1996/06/03  09:04:24  adam
+ * Changed a few logf calls.
+ *
+ * Revision 1.9  1996/03/20  13:54:05  adam
+ * The Tcl_File structure is only manipulated in the Tk-event interface
+ * in tkinit.c.
+ *
+ * Revision 1.8  1996/03/05  09:21:20  adam
+ * Bug fix: memory used by GRS records wasn't freed.
+ * Rewrote some of the error handling code - the connection is always
+ * closed before failback is called.
+ * If failback is defined the send APDU methods (init, search, ...) will
+ * return OK but invoke failback (as is the case if the write operation
+ * fails).
+ * Bug fix: ref_count in assoc object could grow if fraction of PDU was
+ * read.
+ *
+ * Revision 1.7  1996/02/19  15:41:55  adam
+ * Better log messages.
+ * Minor improvement of connect method.
+ *
+ * Revision 1.6  1996/02/06  09:22:54  adam
+ * Ported ir-tcl to use beta releases of tcl7.5/tk4.1.
+ *
+ * Revision 1.5  1995/11/28  13:53:40  quinn
+ * Windows port.
+ *
+ * Revision 1.4  1995/10/17  12:18:59  adam
  * Bug fix: when target connection closed, the connection was not
  * properly reestablished.
