unity完整讀取串口數據方法

使用過一些網上一些大神的代碼後，或多或少都有點小缺陷，關於數據讀取缺失或者一些不太滿意的問題，於是整合了一下。

一次性讀取完整串口數據。

public class PortControl : MonoBehaviour
{
    [Header("串口名")] public string portName = "COM3";
    [Header("波特率")] public int baudRate = 9600;
    [Header("效驗位")] public Parity parity = Parity.None;
    [Header("數據位")] public int dataBits = 8;
    [Header("停止位")] public StopBits stopBits = StopBits.One;

    private SerialPort sp = null;
    private Thread dataReceiveThread;
    private Global global;
    private byte[] datasBytes;

    private string OneString;
    private string OtherString;

    private void Start()
    {
        global = Global.Instance;
        OpenPortControl();
    }
    /// <summary>
    /// 開啓串口
    /// </summary>
    public void OpenPortControl()
    {
        sp = new SerialPort(portName, baudRate, parity, dataBits, stopBits);
        //串口初始化
        if (!sp.IsOpen)
        {
            sp.Open();
        }
        dataReceiveThread = new Thread(ReceiveData);//該線程用於接收串口數據 
        dataReceiveThread.Start();
    }
    /// <summary>
    /// 關閉串口
    /// </summary>
    public void ClosePortControl()
    {
        if (sp != null && sp.IsOpen)
        {
            sp.Close();//關閉串口
            sp.Dispose();//將串口從內存中釋放掉
        }
    }

    private void ReceiveData()
    {
        int bytesToRead = 0;

                    bytesToRead = sp.Read(datasBytes, 0, datasBytes.Length);
                    if (bytesToRead == 0)
                    {
                        continue;
                    }
                    else
                    {

                            Debug.Log(OtherString);

                        //Debug.Log(strbytes);
                    }

                }
