Mojave Electron serialport/bindings/poller error Error: bad file descriptor

[deveind]

Summary of Problem

(Please answer all 3)

• What are you trying to do?
  When disconnecting the USB connection of an open port that was already used for a write command on Mojave 10.14.6 and Electron 1.8.0 nor ERROR or CLOSE Events are thrown
• What happens?
  It can be seen that the debugger throws endless loop traces
  serialport/bindings/poller error Error: bad file descriptor +0ms
  Which brings the process to virtually hang. We also use the USB Library to identify connects and disconnects. But in this case even these handlers are not reached anymore
• What should have happened?
  An error should be thrown or a disconnect or close event

Code to Reproduce the Issue

const transport = function({ comName }) {
  return new Promise((resolve, reject) => {
    // Argument validation
    if (!comName || typeof comName !== 'string') {
      reject(new Error('\"comName\" argument of type String required'))
    }

    // SerialTransport object
    const port = new SerialPort(comName, {
      lock: false,
      baudRate: 57600,
      dataBits: 8,
      stopBits: 1,
      parity: 'odd'
    });

    // SerialTransport events
    port.on('open', function() {
      console.log('Opening port ', comName);
      resolve(port)
    });
    port.on('error', function(error) {
      console.log('Error on port ', comName);
      reject(error)
    });
    port.on('close', function(error) {
      console.log('Close on port ', comName);
      reject(error)
    });
  })
}

module.exports = transport

// Code

Hello

the issue mentioned #1243
and the current Fix request #1803 and #1804 seem to fix also my issue.

1. connect
2. write to a port
3. keep port open
4. unplug USB
5. infinite loop in poller without disconnect or propagation of the error event to a higher level

So my question is when #1804 is going to be merged?
May I help somehow.

Thanks.
