  26  *
  27  *Revision 2.3  1998/03/16 18:01:12  ivan
  28  *changes in the cyclades_port structure to get it closer to the
  29  *standard serial port structure;
  30  *added constants for new ioctls;
  31  *
  32  *Revision 2.2  1998/02/17 16:50:00  ivan
  33  *changes in the cyclades_port structure (addition of shutdown_wait and
  34  *chip_rev variables);
  35  *added constants for new ioctls and for CD1400 rev. numbers.
  36  *
  37  *Revision 2.1  1997/10/24 16:03:00  ivan
  38  *added rflow (which allows enabling the CD1400 special flow control
  39  *feature) and rtsdtr_inv (which allows DTR/RTS pin inversion) to
  40  *cyclades_port structure;
  41  *added Alpha support
  42  *
  43  *Revision 2.0  1997/06/30 10:30:00  ivan
  44  *added some new doorbell command constants related to IOCTLW and
  45  *UART error signaling

  50  *
  51  *Revision 1.7  1997/03/26 10:30:00  daniel
  52  *new entries at the end of cyclades_port struct to reallocate
  53  *variables illegally allocated within card memory.
  54  *
  55  *Revision 1.6  1996/09/09 18:35:30  bentson
  56  *fold in changes for Cyclom-Z -- including structures for
  57  *communicating with board as well modest changes to original
  58  *structures to support new features.
  59  *
  60  *Revision 1.5  1995/11/13 21:13:31  bentson
  61  *changes suggested by Michael Chastain <mec@duracef.shout.net>
