With the constant traffic of the ftdi devices, it just means the light was blinking continuously, regardless of traffic. I'll probably look at having one of the applications that uses the serial port to kick of a transient flicker instead. Thanks kindly for the prompt and useful responses. Sincerely, Karl Palsson
