Jarek,

I created a design for someone and it is problematic. When initial installed with a PN eeg pendant it works fine.
After closing and reopening the design there is a serial port error. Usually it says the port is not available. I checked the device manager to make sure the dongle was assigned properly, which it was, but had to reinstall the device set to make it work correctly. The design worked well after that but after quitting and reloading the same error comes up again. I can not replicate this on my two computers. Is there an issue with the serial port connections that you are aware of? I am thinking it is a problem with the users computer but want to check all avenues

Thanks

George

I am not aware of a problem with serial port. Serial port element is used a lot, most devices operate that way.

This looks to me like some sort of a device driver issue.

SerialPort element has another option which you might want to try: "gnu.io". In my experience it never performed better, but it uses a completely different library to access serial port, so maybe it will help. If it also has the same problem, then this is most likely a problem with the device driver.
