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... -- John-Mark Gurney Voice: +1 541 684 8449 Cu Networking P.O.
