 *Initial revision
15
 *
16
 *Revision 2.5  1998/08/03 16:57:01  ivan
17
 *added cyclades_idle_stats structure;
18
 *
19
 *Revision 2.4  1998/06/01 12:09:53  ivan
20
 *removed closing_wait2 from cyclades_port structure;
21
 *
22
 *Revision 2.3  1998/03/16 18:01:12  ivan
23
 *changes in the cyclades_port structure to get it closer to the
24
 *standard serial port structure;
25
 *added constants for new ioctls;
26
 *
27
 *Revision 2.2  1998/02/17 16:50:00  ivan
28
 *changes in the cyclades_port structure (addition of shutdown_wait and
29
 *chip_rev variables);
30
 *added constants for new ioctls and for CD1400 rev. numbers.
31
 *
32
 *Revision 2.1  1997/10/24 16:03:00  ivan
33
 *added rflow (which allows enabling the CD1400 special flow control
34
 *feature) and rtsdtr_inv (which allows DTR/RTS pin inversion) to
35
 *cyclades_port structure;
36
 *added Alpha support
37
 *
38
 *Revision 2.0  1997/06/30 10:30:00  ivan
39

45
 *
46
 *Revision 1.7  1997/03/26 10:30:00  daniel
47
 *new entries at the end of cyclades_port struct to reallocate
48
 *variables illegally allocated within card memory.
49
 *
50
 *Revision 1.6  1996/09/09 18:35:30  bentson
51
 *fold in changes for Cyclom-Z -- including structures for
52
 *communicating with board as well modest changes to original
53
 *structures to support new features.
54
