我在从频道返回 +CDS 时遇到了麻烦。我正在使用具有 64 个通道的调制解调器，我需要获取此值。以上任何行中缺少的信息

我开始：

public PortaCOM(string porta)
    : base(porta, 115200, Parity.None, 8, StopBits.One)
{
    this.StatusPort = StatusPorta.Ready;
    this.DiscardNull = true;
    this.Handshake = Handshake.RequestToSend;
    //this.RtsEnable = true;
    //this.DtrEnable = true;
    //this.ReadTimeout = 12000;
    //this.ReadTimeout = 12000;
}

我使用以下方法获得价值：

static void p_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
    var p = (PortaCOM)sender;
    try
    {

        int dataLength = p.BytesToRead;
        byte[] dados = new byte[dataLength];
        int nbrDataRead = p.Read(dados, 0, dataLength);
        if (nbrDataRead == 0)
            return;

        var retorno = Encoding.ASCII.GetString(dados);
        Console.WriteLine(retorno);
    }
    catch (Exception err) { Console.WriteLine(err.Message); }
}

请，任何帮助我！

我在 p_DataReceived 内部进行了更改

    static void p_DataReceived(object sender, SerialDataReceivedEventArgs e)
    {
        var p = (PortaCOM)sender;
        try
        {

           **var b = new List<byte>(); 
            while (p.BytesToRead > 0) 
                b.Add((byte)p.ReadByte()); 
            if (b.IsEmpty()) 
                return;**

            var retorno = Encoding.ASCII.GetString(b.ToArray());

            Console.WriteLine(retorno);
        }
        catch (Exception err) { Console.WriteLine(err.Message); }
    }
