hi, we are seeing a problem which we suspect *may* be an intermittent serial port lockup on the 8051 series. We have an 8051-based device which quits communicating sometimes. Basically we suspect that another component is holding the serial port in the low (break) state for prolonged periods of time and are wondering if anyone knew of any problems with doing this. We are in the process of fixing the other component to not behave this way, but are looking to see if we can gain any confidence that this may actually fix the problem with the 8051-based device.
