- *$Log: cyclades.h,v $
- *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

- *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

- *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
