Hardware handshaking issues.

+behaviour is specialix.sx_rtscts = 0 where the pin behaves as DTR when
hardware handshaking is off. It behaves as the RTS hardware
handshaking signal when hardware handshaking is selected.
software handshaking. So switching on the fly is not really an
option.
-I actually prefer to use the "Specialix DTR/RTS pin is RTS" option.
+I actually prefer to use the "specialix.sx_rtscts=1" option.
This makes the DTR/RTS pin always an RTS pin, and ioctls to
change DTR are always ignored. I have a cable that is configured
for this.
You have to WRITE to the address register to even
read-probe a CD186x register. Disable autodetection?
-- Specialix: any suggestions?
- - Arbitrary baud rates are not implemented yet.
- If you need this, bug me about it.

+ * The Maxim's MAX7301 device is an SPI driven GPIO expander. There are

+ * Note:
+ * - DIN must be stable at the rising edge of clock.
+ * - when writing:
+ * - always clock in 16 clocks at once
+ * - at DIN: D15 first, D0 last
+ * - D0..D7 = databyte, D8..D14 = commandbyte
+ * - D15 = low -> write command
+ * - when reading
+ * - always clock in 16 clocks at once
+ * - at DIN: D15 first, D0 last
+ * - D0..D7 = dummy, D8..D14 = register address
+ * - D15 = high -> read command
+ * - raise CS and assert it again
+ * - always clock in 16 clocks at once
+ * - at DOUT: D15 first, D0 last
+ * - D0..D7 contains the data from the first cycle
+ *
+ * The driver exports a standard gpiochip interface

- * Fixed problem where setting or retreiving the serial config would fail with
- * EPIPE. Removed CRTS toggling so the driver behaves more like other usbserial
- * adapters. Issued new interval of 1ms instead of the default 10ms. As a
- * result, transfer speed has been substantially increased. From avg. 850bps to
- * avg. 3300bps. initial termios has also been modified. Cleaned up code and
- * formatting issues so it is more readable. Replaced the C++ style comments.

Code in this driver inspired by and in a number of places taken
from Brian Warner's original Keyspan-PDA driver.
This driver has been put together with the support of Innosys, Inc.
and Keyspan, Inc the manufacturers of the Keyspan USB-serial products.
Thanks Guys :)

Thanks to Paulus for miscellaneous tidy ups, some largish chunks
of much nicer and/or completely new code and (perhaps most uniquely)
having the patience to sit down and explain why and where he'd changed
- stuff.
