so, Cyclades (cy) presents an interface similar to sio but ISN'T the sio
drive...  we just need to write a driver for the USB serial devices
that present the same interface as the sio to get a compatible device
driver...  sio isn't designed to handle a smart device over usb.. it's
designed to interface w/ the family of 8250 IC chips and nothing more...
