我正在使用 C# 的SerialPort
类尝试向AT
设备发送命令并获得响应。我已经验证它在超级终端中正常工作,如果我发送它的命令,AT
它会以OK
. 但是,在我的控制台应用程序中,如果我发送AT
,它会回复一个 echo AT
。代码如下,任何了解我在接收代码中做错了什么都将不胜感激:
ComPort.DataReceived += new SerialDataReceivedEventHandler(ComPort_DataReceived);
public void Open()
{
Console.WriteLine();
//close port if already open.
if (ComPort.IsOpen)
{
ComPort.Close();
}
//setup port.
ComPort.PortName = ConfigurationManager.AppSettings["PortName"].ToString();
ComPort.BaudRate = Convert.ToInt32(ConfigurationManager.AppSettings["BaudRate"]);
ComPort.Parity = Parity.None;
ComPort.StopBits = StopBits.One;
ComPort.DataBits = 8;
ComPort.DtrEnable = true;
ComPort.RtsEnable = true;
if (Convert.ToBoolean(ConfigurationManager.AppSettings["HWFlowControlEnabled"]))
{
ComPort.Handshake = Handshake.RequestToSend;
}
//open port.
Console.WriteLine("Opening port " + ComPort.PortName + "...");
ComPort.Open();
Console.WriteLine("Opened port " + ComPort.PortName);
}
void ComPort_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
string message = ComPort.ReadExisting();
Console.WriteLine("RECEIVED: " + message);
if (message.IndexOf("OK") > -1)
{
ReceivedOK = true;
}
}
