Trying to receive values from Arduino to Unity

I made SerialHandler.cs for connecting Arduino via serial connection.

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

public class SerialHandler : MonoBehaviour {
    public delegate void SerialDataReceivedEventHandler (string message);
    public event SerialDataReceivedEventHandler OnDataReceived = delegate { };

    //Port name
    public string portName = "/dev/tty.usbmodem1412101";
    public int baudRate = 9600;

    private SerialPort serialPort_;
    private Thread thread_;
    private bool isRunning_ = false;

    private string message_;
    private bool isNewMessageReceived_ = false;

    void Awake () {
        Open ();
    }

    void Update () {
        if (isNewMessageReceived_) {
            OnDataReceived (message_);
        }
        Debug.Log (message_);

        isNewMessageReceived_ = false;
    }

    void OnDestroy () {
        Close ();
    }

    private void Open () {
        serialPort_ = new SerialPort (portName, baudRate, Parity.None, 8, StopBits.One);
        // Or
        //serialPort_ = new SerialPort(portName, baudRate);
        serialPort_.Open ();
        serialPort_.NewLine = "\\n";

        isRunning_ = true;

        thread_ = new Thread (Read);
        thread_.Start ();
    }

    private void Close () {
        isNewMessageReceived_ = false;
        isRunning_ = false;

        if (thread_ != null && thread_.IsAlive) {
            thread_.Join ();
        }

        if (serialPort_ != null && serialPort_.IsOpen) {
            serialPort_.Close ();
            serialPort_.Dispose ();
        }
    }

    private void Read () {
        while (isRunning_ && serialPort_ != null && serialPort_.IsOpen) {
            try {
                message_ = serialPort_.ReadLine ();
                isNewMessageReceived_ = true;
            } catch (System.Exception e) {
                Debug.LogWarning (e.Message);
            }
        }
    }

    public void Write (string message) {
        try {
            serialPort_.Write (message);
        } catch (System.Exception e) {
            Debug.LogWarning (e.Message);
        }
    }
}

And also I wrote an another code for the object inside Unity.

It's called DoSomething.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class DoSomething : MonoBehaviour {
    //先ほど作成したクラス
    public SerialHandler serialHandler;

    void Start () {
        //信号を受信したときに、そのメッセージの処理を行う
        // serialHandler.OnDataReceived += OnDataReceived;
    }

    void Update () {
        //文字列を送信
        // serialHandler.Write ("hogehoge");
    }

    //受信した信号(message)に対する処理
    void OnDataReceived (string message) {
        var data = message.Split (
            new string[] { "\\t" }, System.StringSplitOptions.None);
        if (data.Length < 2) return;

        try {
            // try here
            Debug.Log (data);
        } catch (System.Exception e) {
            Debug.LogWarning (e.Message);
        }
    }
}
