+/*
+ * Definitions for the FTDI USB Single Port Serial Converter -
+ * known as FTDI_SIO (Serial Input/Output application of the chipset)
+ *
+ * The example I have is known as the USC-1000 which is available from
+ * http://www.dse.co.nz - cat no XH4214 It looks similar to this:
+ * http://www.dansdata.com/usbser.htm but I can't be sure There are other
+ * USC-1000s which don't look like my device though so beware!
+ *
+ * The device is based on the FTDI FT8U100AX chip. It has a DB25 on one side,
+ * USB on the other.
+ *
+ * Thanx to FTDI (http://www.ftdi.co.uk) for so kindly providing details
+ * of the protocol required to talk to the device and ongoing assistence
+ * during development.
+ *
+ * Bill Ryder - bryder@sgi.com of Silicon Graphics, Inc.- wrote the
+ * FTDI_SIO implementation.
