+/*
+ * cy.c
+ *
+ * Driver for Cyclades Cyclom-8/16/32 multiport serial cards
+ * (currently not tested with Cyclom-32 cards)
+ *
+ * Timo Rossi, 1996
+ *
+ * Supports both ISA and PCI Cyclom cards
+ *
+ * Uses CD1400 automatic CTS flow control, and
+ * if CY_HW_RTS is defined, uses CD1400 automatic input flow control.
+ * This requires a special cable that exchanges the RTS and DTR lines.
+ *
+ * Lots of debug output can be enabled by defining CY_DEBUG
+ * Some debugging counters (number of receive/transmit interrupts etc.)
+ * can be enabled by defining CY_DEBUG1
+ *
+ * This version uses the bus_mem/io_??() stuff
+ *
+ * NOT TESTED !!!
+ *
