GetOverlappedResult: Operation Aborted on some Windows 10/11 machines

[cerilloderek]

I'm working on an electron app to communicate with multiple UART devices. Some remote users on Windows 10 and 11 machines have had a js error popup with this error:

This popup doesn't seem to adversely impact users ability to interact with devices but it does popup whenever trying to write to the port the device is connected to. So it's rather annoying. I've been unable to reproduce it myself on any computer/device combination available to me.

I saw this post: #2405 and a couple issues in github but they didn't seem to be directly related.

I've changed our code a little bit to obfuscate business logic, but this is the gist of it

const portInfos = await SerialPort.list()
// some logic to filter down to ports we want to show to users
for { porrtInfo of portInfos) {
  const port = new SerialPort(portInfo.path, {
    baudRate: 250000,
    autoOpen: false,
  }) ;
  const parser = new Readline();
  port.open((err) => {
    if (err) {
    // some error handling
    }
  });
  port.pipe(parser);
  port.on('close', () => {
    this.handleSerialClose(port.path);
  });
  parser.on('data', (datastr: string) => {
    this.handleIncomingSerial(datastr, port.path);
  });
}

// API that allows writing to port from other classes and stuff
const send = (strToSend) => {
  port.write(strToSend} + '\n'); // port here is one of the ports opened above^
}

We don't limit or throttle writing to ports, so that's one area we could try to improve if that would affect reducing overlapped writes. We also don't drain or flush the port at any point. Additionally, it doesn't seem we are using an error callback for our write calls to the ports, though I don't think the JS error above would be caught by that in the first place... Additionally, the UART devices don't have any flow control enabled at all, so could this be related to that?

Happy to give any more context or code (that I'm allowed to share).

Thanks for the great product, been working great for our uses!
