/*
 * 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
 * wLength:        0
 * 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).
