3 * known as FTDI_SIO (Serial Input/Output application of the chipset)
5 * The example I have is known as the USC-1000 which is available from
6 * http://www.dse.co.nz - cat no XH4214 It looks similar to this:
7 * http://www.dansdata.com/usbser.htm but I can't be sure There are other
8 * USC-1000s which don't look like my device though so beware!
10 * The device is based on the FTDI FT8U100AX chip. It has a DB25 on one side,
13 * Thanx to FTDI (http://www.ftdi.co.uk) for so kindly providing details
14 * of the protocol required to talk to the device and ongoing assistence
17 * Bill Ryder - bryder@sgi.com formerly of Silicon Graphics, Inc.- wrote the
18 * FTDI_SIO implementation.
20 * Philipp Gühring - pg@futureware.at - added the Device ID of the USB relais

323 * wValue: BaudDivisor value - see below
327 * The BaudDivisor values are calculated as follows:
328 * - BaseClock is either 12000000 or 48000000 depending on the device. FIXME: I wish
329 * I knew how to detect old chips to select proper base clock!
330 * - BaudDivisor is a fixed point number encoded in a funny way.
331 * (--WRONG WAY OF THINKING--)
332 * BaudDivisor is a fixed point number encoded with following bit weighs:
333 * (-2)(-1)(13..0). It is a radical with a denominator of 4, so values
334 * end with 0.0 (00...), 0.25 (10...), 0.5 (01...), and 0.75 (11...).
336 * The both-bits-set has quite different meaning from 0.75 - the chip designers
337 * have decided it to mean 0.125 instead of 0.75.
338 * This info looked up in FTDI application note "FT8U232 DEVICES \ Data Rates
339 * and Flow Control Consideration for USB to RS232".
340 * - BaudDivisor = (BaseClock / 16) / BaudRate, where the (=) operation should
341 * automagically re-encode the resulting value to take fractions into consideration.
342 * As all values are integers, some bit twiddling is in order:
343 * BaudDivisor = (BaseClock / 16 / BaudRate) |
344 * (((BaseClock / 2 / BaudRate) & 4) ? 0x4000 // 0.5
345 * : ((BaseClock / 2 / BaudRate) & 2) ? 0x8000 // 0.25
346 * : ((BaseClock / 2 / BaudRate) & 1) ? 0xc000 // 0.125
349 * For the FT232BM, a 17th divisor bit was introduced to encode the multiples
350 * of 0.125 missing from the FT8U232AM. Bits 16 to 14 are coded as follows
351 * (the first four codes are the same as for the FT8U232AM, where bit 16 is
353 * 000 - add .000 to divisor
354 * 001 - add .500 to divisor
355 * 010 - add .250 to divisor
356 * 011 - add .125 to divisor
357 * 100 - add .375 to divisor
358 * 101 - add .625 to divisor
359 * 110 - add .750 to divisor
360 * 111 - add .875 to divisor
361 * Bits 15 to 0 of the 17-bit divisor are placed in the urb value. Bit 16 is
362 * placed in bit 0 of the urb index.
364 * Note that there are a couple of special cases to support the highest baud
365 * rates. If the calculated divisor value is 1, this needs to be replaced with
366 * 0. Additionally for the FT232BM, if the calculated divisor value is 0x4001
367 * (1.5), this needs to be replaced with 0x0001 (1) (but this divisor value is
368 * not supported by the FT8U232AM).
389 } FTDI_SIO_baudrate_t ;
392 * The ftdi_8U232AM_xxMHz_byyy constants have been removed. The encoded divisor values
393 * are calculated internally.

497 * B0 Output handshaking using RTS/CTS

503 * B2 Xon/Xoff handshaking
507 * A value of zero in the hIndex field disables handshaking
509 * If Xon/Xoff handshaking is specified, the hValue field should contain the XOFF character
510 * and the lValue field contains the XON character.
514 * FTDI_SIO_GET_LATENCY_TIMER
516 * Set the timeout interval. The FTDI collects data from the slave
517 * device, transmitting it to the host when either A) 62 bytes are
518 * received, or B) the timeout interval has elapsed and the buffer
519 * contains at least 1 byte. Setting this value to a small number
520 * can dramatically improve performance for applications which send
521 * small packets, since the default value is 16ms.
