10 *Revision 3.1 2002/01/29 11:36:16 henrique
11 *added throttle field on struct cyclades_port to indicate whether the
12 *port is throttled or not
13 *
14 *Revision 3.1 2000/04/19 18:52:52 ivan
15 *converted address fields to unsigned long and added fields for physical
16 *addresses on cyclades_card structure;
17 *
18 *Revision 3.0 1998/11/02 14:20:59 ivan
19 *added nports field on cyclades_card structure;
20 *

25 *removed closing_wait2 from cyclades_port structure;
26 *
27 *Revision 2.3 1998/03/16 18:01:12 ivan
28 *changes in the cyclades_port structure to get it closer to the
29 *standard serial port structure;
30 *added constants for new ioctls;
31 *
32 *Revision 2.2 1998/02/17 16:50:00 ivan
33 *changes in the cyclades_port structure (addition of shutdown_wait and
34 *chip_rev variables);
35 *added constants for new ioctls and for CD1400 rev. numbers.
36 *
37 *Revision 2.1 1997/10/24 16:03:00 ivan
38 *added rflow (which allows enabling the CD1400 special flow control
39 *feature) and rtsdtr_inv (which allows DTR/RTS pin inversion) to
40 *cyclades_port structure;
41 *added Alpha support
42 *
43 *Revision 2.0 1997/06/30 10:30:00 ivan
44 *added some new doorbell command constants related to IOCTLW and
45 *UART error signaling
46 *
47 *Revision 1.8 1997/06/03 15:30:00 ivan
48 *added constant ZFIRM_HLT

54 *
55 *Revision 1.6 1996/09/09 18:35:30 bentson
56 *fold in changes for Cyclom-Z -- including structures for
57 *communicating with board as well modest changes to original
58 *structures to support new features.
59 *
60 *Revision 1.5 1995/11/13 21:13:31 bentson
