NAME
     cy — Cyclades Cyclom-{4, 8, 16, 32}Y asynchronous comms board serial
     device driver

SYNOPSIS
     cy0 at isa? iomem 0xd4000 irq 12
     cy* at pci? dev ? function ?

DESCRIPTION
     This driver provides an interface to Cyclades Cyclom-4Y, Cyclom-8Y,
     Cyclom-16Y, and Cyclom-32Y asynchronous multiport serial boards.  These
     boards are based around Cirrus Logic CD1400 communication controllers.

     The device minor numbers for this driver are encoded as follows:

	 d c c p p p p p     - bits in the minor device number

	 bits	 meaning
	 ----	 -------
	 ppppp	 physical serial line (i.e. port) to use:
		     0-3 on Cyclom-4Y
		     0-7 on Cyclom-8Y
		     0-15 on Cyclom-16Y
		     0-31 on Cyclom-32Y

	 cc	 card unit number; note this limits the driver to
		 four cards per system

	 d	 set to use as a dial-out line

FLOW CONTROL
     The cy driver makes use of the CD1400's automatic CTS flow control.  In
     addition, the CD1400's automatic input flow control can be used.  This
     requires the kernel configuration option CY_HW_RTS and a special cable
     that exchanges the RTS and DTR lines.

DIAGNOSTICS
     cy%d: port %d: can't allocate tty	There is not enough memory to allocate
     tty data structures.

     cy%d: can't allocate input buffer	There is not enough memory to allocate
     the data input buffer.

     Additional debugging output can be enable with the kernel configuration
     option CY_DEBUG.  Diagnostic counters may be enabled with the kernel con‐
     figuration option CY_DEBUG1.

SEE ALSO
     termios(4), tty(4)

AUTHORS
     The cy driver was written by Timmo Rossi.

BUGS
     Support for the Cyclom-32Y has not been tested.
