 *$Log: not supported by cvs2svn $

 *Revision 1.1.1.1  2001/07/02 17:57:56  simons

 *Initial revision

 *

 *Revision 2.5  1998/08/03 16:57:01  ivan

 *added cyclades_idle_stats structure;

 *

 *Revision 2.4  1998/06/01 12:09:53  ivan

 *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

 *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>

 *to support use of this file in non-kernel applications
