- * cyy_interrupt was changed to avoid occurrence of kernel oopses - * during PPP operation. - * - * Revision 2.2.1.3 1998/06/01 12:09:10 ivan - * General code review in order to comply with 2.1 kernel standards; - * data loss prevention for slow devices revisited (cy_wait_until_sent - * was created); - * removed conditional compilation for new/old PCI structure support - * (now the driver only supports the new PCI structure). - * - * Revision 2.2.1.1 1998/03/19 16:43:12 ivan - * added conditional compilation for new/old PCI structure support; - * removed kernel series (2.0.x / 2.1.x) conditional compilation. - * - * Revision 2.1.1.3 1998/03/16 18:01:12 ivan - * cleaned up the data loss fix; - * fixed XON/XOFF handling once more (Cyclades-Z); - * general review of the driver routines; - * introduction of a mechanism to prevent data loss with slow - * printers, by forcing a delay before closing the port. - * - * Revision 2.1.1.2 1998/02/17 16:50:00 ivan - * fixed detection/handling of new CD1400 in Ye boards; - * fixed XON/XOFF handling (Cyclades-Z); - * fixed data loss caused by a premature port close; - * introduction of a flag that holds the CD1400 version ID per port - * (used by the CYGETCD1400VER new ioctl). |
