If a machine doesn't provide flow control can't you over-run the buffers if the machine gets loaded down and the interrupt load gets so bad that the sio interrupt handler isn't called enough. However, if you use flow control shouldn't it stop the buffer from getting overflowed simply because no more data is being received. Am I totally out to lunch here? I know that I get lots of silo over-flows when I don't use flow control and push the line fast, where as soon as I turn on flow control they go away. Nate
