Thanks for your help and reference to Developer's forum. There is around 70 forums. I try to find one with "driver" related without success. Please, may somebody point out which forum could be the start point?
About my problem, I just update as below:
The N3060 and E8000 are two SoC that "implements two instances of high speed UART controller that support baud rates between 300 and 3686400 (hardware flow control is also supported)" .
According with Microsoft, "All versions of Windows provide driver support for serial controller devices. The term serial controller refers to a 16550 universal asynchronous receiver-transmitter (UART) or compatible device. A serial controller has a serial port through which it communicates with a serially connected peripheral device. To support serial communication, Windows includes the Serial.sys and Serenum.sys drivers, and versions 1 and 2 of the serial framework extension (SerCx and SerCx2)" .
In the Download Center of Intel , the keywords: 16650, uart, serial port, don't give any result.
In other hand, our motherboard provider said that Intel doesn't support the internal UART and we must use the external Super I/O (NCT6102).
What is my example missing?
What site should I have checked?
You are more than welcome!
Hopefully, you will get the proper support at that website, if not, let me know and I will see what else I can do for you.
