29 *
30 *Revision 2.3  1998/03/16 18:01:12  ivan
31 *changes in the cyclades_port structure to get it closer to the
32 *standard serial port structure;
33 *added constants for new ioctls;
34 *
35 *Revision 2.2  1998/02/17 16:50:00  ivan
36 *changes in the cyclades_port structure (addition of shutdown_wait and
37 *chip_rev variables);
38 *added constants for new ioctls and for CD1400 rev. numbers.
39 *
40 *Revision 2.1	1997/10/24 16:03:00  ivan
41 *added rflow (which allows enabling the CD1400 special flow control
42 *feature) and rtsdtr_inv (which allows DTR/RTS pin inversion) to
43 *cyclades_port structure;
44 *added Alpha support
45 *
46 *Revision 2.0  1997/06/30 10:30:00  ivan
47 *added some new doorbell command constants related to IOCTLW and
48 *UART error signaling
49 *
50 *Revision 1.8  1997/06/03 15:30:00  ivan
51 *added constant ZFIRM_HLT
52 *added constant CyPCI_Ze_win ( = 2 * Cy_PCI_Zwin)
53 *
54 *Revision 1.7  1997/03/26 10:30:00  daniel
55 *new entries at the end of cyclades_port struct to reallocate
56 *variables illegally allocated within card memory.
57 *
58 *Revision 1.6  1996/09/09 18:35:30  bentson
59 *fold in changes for Cyclom-Z -- including structures for
60 *communicating with board as well modest changes to original
61 *structures to support new features.
62 *
63 *Revision 1.5  1995/11/13 21:13:31  bentson
64 *changes suggested by Michael Chastain <mec@duracef.shout.net>
65 *to support use of this file in non-kernel applications
