Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+/*
+ * 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 formerly of Silicon Graphics, Inc.- wrote the
+ * FTDI_SIO implementation.
+ *
+ * Philipp Gühring - pg@futureware.at - added the Device ID of the USB relais
+ * from Rudolf Gugler

+ * wValue: BaudDivisor value - see below
+ * wIndex: Port

+ * Data: None
+ * The BaudDivisor values are calculated as follows:
+ * - BaseClock is either 12000000 or 48000000 depending on the device. FIXME: I wish
+ * I knew how to detect old chips to select proper base clock!
+ * - BaudDivisor is a fixed point number encoded in a funny way.
+ * (--WRONG WAY OF THINKING--)
+ * BaudDivisor is a fixed point number encoded with following bit weighs:
+ * (-2)(-1)(13..0). It is a radical with a denominator of 4, so values
+ * end with 0.0 (00...), 0.25 (10...), 0.5 (01...), and 0.75 (11...).
+ * (--THE REALITY--)
+ * The both-bits-set has quite different meaning from 0.75 - the chip designers
+ * have decided it to mean 0.125 instead of 0.75.
+ * This info looked up in FTDI application note "FT8U232 DEVICES \ Data Rates
+ * and Flow Control Consideration for USB to RS232".
+ * - BaudDivisor = (BaseClock / 16) / BaudRate, where the (=) operation should
+ * automagically re-encode the resulting value to take fractions into consideration.
+ * As all values are integers, some bit twiddling is in order:
+ * BaudDivisor = (BaseClock / 16 / BaudRate) |
+ * (((BaseClock / 2 / BaudRate) & 4) ? 0x4000 // 0.5
+ * : ((BaseClock / 2 / BaudRate) & 2) ? 0x8000 // 0.25
+ * : ((BaseClock / 2 / BaudRate) & 1) ? 0xc000 // 0.125
+ * : 0)
+ *
+ * For the FT232BM, a 17th divisor bit was introduced to encode the multiples
+ * of 0.125 missing from the FT8U232AM. Bits 16 to 14 are coded as follows
+ * (the first four codes are the same as for the FT8U232AM, where bit 16 is
+ * always 0):
+ * 000 - add .000 to divisor
+ * 001 - add .500 to divisor
+ * 010 - add .250 to divisor
+ * 011 - add .125 to divisor
+ * 100 - add .375 to divisor
+ * 101 - add .625 to divisor
+ * 110 - add .750 to divisor
+ * 111 - add .875 to divisor
+ * Bits 15 to 0 of the 17-bit divisor are placed in the urb value. Bit 16 is
+ * placed in bit 0 of the urb index.
+ *
+ * Note that there are a couple of special cases to support the highest baud
+ * rates. If the calculated divisor value is 1, this needs to be replaced with
+ * 0. Additionally for the FT232BM, if the calculated divisor value is 0x4001
+ * (1.5), this needs to be replaced with 0x0001 (1) (but this divisor value is
+ * not supported by the FT8U232AM).
