❔ Serial Communication

Hi. Nothing is being printed to the console and I have no idea why.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO.Ports;

public class ArduinoController : MonoBehaviour
{
    SerialPort serial;

    void Start() //called once when the program is run
    {
        serial = new SerialPort("COM3", 9600);
        serial.Open();
    }

    void Update() //called once every frame
    {
        string data = serial.ReadLine();
        Debug.Log(data);
    }
}

❔ crashing

Any idea how to prevent this code from crashing unity?

    SerialPort sp = new SerialPort("COM3", 9600);
sp.Open();

    While true()
    {
        if (sp.IsOpen)
        {
            try
            {
                serialEvent(sp);
            }
            catch (Exception)
            {
                throw;
            }
        }

    }

    void serialEvent(SerialPort myPort)
    {
        string myString = myPort.ReadLine();
        if (myString != null)
        {
                Debug.Log("Read " + myString);
        }
    }

    SerialPort sp = new SerialPort("COM3", 9600);
sp.Open();

    While true()
    {
        if (sp.IsOpen)
        {
            try
            {
                serialEvent(sp);
            }
            catch (Exception)
            {
                throw;
            }
        }

    }

    void serialEvent(SerialPort myPort)
    {
        string myString = myPort.ReadLine();
        if (myString != null)
        {
                Debug.Log("Read " + myString);
        }
    }
