| *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 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 |
| *added constant ZFIRM_HLT |
| *added constant CyPCI_Ze_win ( = 2 * Cy_PCI_Zwin) |
| * |
| *Revision 1.7 1997/03/26 10:30:00 daniel |
| *new entries at the end of cyclades_port struct to reallocate |
| *variables illegally allocated within card memory. |
| * |
| *Revision 1.6 1996/09/09 18:35:30 bentson |
| *fold in changes for Cyclom-Z -- including structures for |
| *communicating with board as well modest changes to original |
| *structures to support new features. |
| * |
| *Revision 1.5 1995/11/13 21:13:31 bentson |
| *changes suggested by Michael Chastain <mec@duracef.shout.net> |
