            });


            var cmd = $"*2{Environment.NewLine}$4{Environment.NewLine}info{Environment.NewLine}$3{Environment.NewLine}all{Environment.NewLine}";

            Console.WriteLine($"cmd:{cmd}");

            var data = Encoding.UTF8.GetBytes(cmd);

            ns.Write(data, 0, data.Length);

            Console.WriteLine($"cmd:sended");


            Console.ReadLine();
        }
    }
}

有谁知道发生了什么？ 谢谢

这是windows和centens7的运行效果图

此打印为windows服务器，centos7客户端数据传输
