13 * Changed a few logf calls.
15 * Revision 1.9 1996/03/20 13:54:05 adam
16 * The Tcl_File structure is only manipulated in the Tk-event interface
19 * Revision 1.8 1996/03/05 09:21:20 adam
20 * Bug fix: memory used by GRS records wasn't freed.
21 * Rewrote some of the error handling code - the connection is always
22 * closed before failback is called.
23 * If failback is defined the send APDU methods (init, search, ...) will
24 * return OK but invoke failback (as is the case if the write operation
26 * Bug fix: ref_count in assoc object could grow if fraction of PDU was
29 * Revision 1.7 1996/02/19 15:41:55 adam
