TK103 GPS的TCP / IP服务器

Question

我正在开发TCP / IP服务，以读取GPS（TK 103）发送的数据。这是我在网上找到的一个示例后编写的代码：

static void Main(string[] args)
    {
        TcpListener server = null;
        HttpClient httpClient = new HttpClient();
        try
        {

            Int32 port = 20222;

            IPAddress localAddr = IPAddress.Parse("127.0.0.1");

            server = new TcpListener(port);

            server.Start();

            string data = "";

            while (true)
            {
                Console.WriteLine("Server is listening on " + server.LocalEndpoint);

                Console.WriteLine("Waiting for a connection...");
                var client = server.AcceptTcpClient();

                Console.WriteLine("Connected...");
                NetworkStream stream = client.GetStream();
                byte[] bytesToRead = new byte[client.ReceiveBufferSize];
                int bytesRead = stream.Read(bytesToRead, 0, client.ReceiveBufferSize);

                data = Encoding.ASCII.GetString(bytesToRead, 0, bytesRead);
                Console.WriteLine(data);
            }
        }
    }

从理论上讲，这应该返回以下内容： ##，imei：xxxxx，A;

但这是返回的内容： xx \ r \ u0001 \ u0003Xh？\ 0U \ u0016 \ b \ 0 \ u001e ?? \ r \ n

我尝试了不同的编码，但是没有用。
