Describe the problem

Frequent reading and writing of the serial port causes a blue screen in the window

To reproduce

Port interface：
// Stores data received from the serial port into the provided byte array
// buffer. The function returns the number of bytes read.
//
// The Read function blocks until (at least) one byte is received from
// the serial port or an error occurs.
Read(p []byte) (n int, err error)

// Send the content of the data byte array to the serial port.
// Returns the number of bytes written.
Write(p []byte) (n int, err error)

Thanks for your report @jinronga!

Please provide the source code of a complete minimal Go program that produces the BSoD.

Please also tell us which version of the CH340 driver you have installed. You can find this information by the following procedure:

1. Connect the device that produces the serial port you are using when the fault occurs to your computer.
2. Open the Windows Device Manager.
3. Select View > Devices by type from the Device Manager menus.
4. Open the "View" menu.
5. If there is a ✓ to the left of the "Show hidden devices" menu item, click on "Show hidden devices" to disable it.
6. Open the "Ports (COM & LPT)" section of the Device Manager tree.
7. You should see a port identified as "USB-SERIAL CH340 (COMn)" under the "Ports (COM & LPT)" section (where "COMn" is some serial port e.g., COM4). Double click on that item.
   The "USB-SERIAL CH340 (COMn) Properties" dialog will open.
8. Select the "Driver" tab of the "USB-SERIAL CH340 (COMn) Properties" dialog.

You will see the version in the "Driver Version" field of the dialog.
