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.
Additional debugging output can be enable with the kernel configuration option CY_DEBUG. Diagnostic counters may be enabled with the kernel configuration option CY_DEBUG1.
cy driver was written by Timmo Rossi.
