Serial.list does not update.

Most appropriate sub-area of Processing 4?

Events, IO

Processing version

4.4.7

Operating system

Windows 10

Bug description

I noticed that when you physically remove a connected serial device processing does not detect it and serial.list() does not update.

Steps to reproduce this

1.connect serial device.

2.run below sketch (set correct serial port).

3.unplug serial device.

snippet

import processing.serial.*;

Serial myPort;  // Create object from Serial class

void setup() 
{
  size(200, 200);

  String portName = Serial.list()[0];
  myPort = new Serial(this, portName, 9600);
}

void draw()
{
  println(Serial.list());
  delay(500);
}

Additional context

The https://fazecast.github.io/jSerialComm/ library can detect hardware disconnects.

Would you like to work on the issue?

No, I’m just reporting the issue

Start with the Serial.list() entry point and reproduce the Windows 10 behavior using the provided Processing sketch, then inspect how connected ports are discovered and refreshed after unplugging a device. The issue is done when Serial.list() reflects the removed device without restarting the sketch; jSerialComm is noted as a comparison for disconnect detection.
