+ * 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
