/* $OpenBSD: cy_isa.c,v 1.2 1996/11/12 20:30:28 niklas Exp $ */
/*
* 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 !!!
*
