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

| *removed closing_wait2 from cyclades_port structure; |
| * |
| *Revision 2.3 1998/03/16 18:01:12 ivan |
| *changes in the cyclades_port structure to get it closer to the |
| *standard serial port structure; |
| *added constants for new ioctls; |
| * |
| *Revision 2.2 1998/02/17 16:50:00 ivan |
| *changes in the cyclades_port structure (addition of shutdown_wait and |
| *chip_rev variables); |
| *added constants for new ioctls and for CD1400 rev. numbers. |
| * |
| *Revision 2.1 1997/10/24 16:03:00 ivan |
| *added rflow (which allows enabling the CD1400 special flow control |
| *feature) and rtsdtr_inv (which allows DTR/RTS pin inversion) to |
| *cyclades_port structure; |
| *added Alpha support |
| * |
| *Revision 2.0 1997/06/30 10:30:00 ivan |
| *added some new doorbell command constants related to IOCTLW and |
| *UART error signaling |
| * |
| *Revision 1.8 1997/06/03 15:30:00 ivan |
