9 | * This file contains the general definitions for the cyclades.c driver | |
10 | *$Log: cyclades.h,v $ | |
11 | *Revision 3.1 2002/01/29 11:36:16 henrique | |
12 | *added throttle field on struct cyclades_port to indicate whether the | |
13 | *port is throttled or not | |
14 | * | |
15 | *Revision 3.1 2000/04/19 18:52:52 ivan | |
16 | *converted address fields to unsigned long and added fields for physical | |
17 | *addresses on cyclades_card structure; | |
18 | * | |
19 | *Revision 3.0 1998/11/02 14:20:59 ivan | |
20 | *added nports field on cyclades_card structure; | |
21 | * | |
22 | *Revision 2.5 1998/08/03 16:57:01 ivan | |
23 | *added cyclades_idle_stats structure; | |
24 | * | |
25 | *Revision 2.4 1998/06/01 12:09:53 ivan | |
26 | *removed closing_wait2 from cyclades_port structure; | |
27 | * | |
28 | *Revision 2.3 1998/03/16 18:01:12 ivan | |
29 | *changes in the cyclades_port structure to get it closer to the | |
30 | *standard serial port structure; | |
31 | *added constants for new ioctls; | |
32 | * | |
33 | *Revision 2.2 1998/02/17 16:50:00 ivan | |
34 | *changes in the cyclades_port structure (addition of shutdown_wait and | |
35 | *chip_rev variables); | |
36 | *added constants for new ioctls and for CD1400 rev. numbers. | |
37 | * | |
38 | *Revision 2.1 1997/10/24 16:03:00 ivan | |
39 | *added rflow (which allows enabling the CD1400 special flow control | |
40 | *feature) and rtsdtr_inv (which allows DTR/RTS pin inversion) to | |
41 | *cyclades_port structure; | |
42 | *added Alpha support | |
43 | * | |
44 | *Revision 2.0 1997/06/30 10:30:00 ivan | |
45 | *added some new doorbell command constants related to IOCTLW and | |
46 | *UART error signaling | |

51 | * | |
52 | *Revision 1.7 1997/03/26 10:30:00 daniel | |
53 | *new entries at the end of cyclades_port struct to reallocate | |
54 | *variables illegally allocated within card memory. | |
55 | * | |
56 | *Revision 1.6 1996/09/09 18:35:30 bentson | |
57 | *fold in changes for Cyclom-Z -- including structures for | |
58 | *communicating with board as well modest changes to original | |
59 | *structures to support new features. | |
60 | * | |
61 | *Revision 1.5 1995/11/13 21:13:31 bentson | |
62 | *changes suggested by Michael Chastain <mec@duracef.shout.net> | |
