You'll certainly have no trouble with the ftdi 4232. I've tested those at 6mpbs in both directions concurrently without any data loss. IMO, breaking free of the 115200 barrier is long overdue, but it would have been nice if the step up everyone took was to 921600, because virtually all usb-serial support that. With line-level rather than ttl-level adapters, 1mpbs is often the effective speed limit because of the cheap rs232 line-level chips they use. -- Ian
