But I can't say from actual experience or reading the source. Something else to watch for: the actual 16650 had, if I recall correctly, an eight byte fifo for each direction. Later versions have larger fifos. The larger the fifo, the longer the chip can go between interrupts without loosing data. I don't know if your application will require the larger fifos, but it's something to keep in mind. -- Charles Curley /"\ ASCII Ribbon Campaign Looking for fine software \ / Respect for open standards and/or writing?
