通过诺基亚手机的短信通过串口 [英] Sms via a nokia phone over a serial port

问题描述

我试图通过诺基亚手机通过串行这是通过腻子很容易发送短信。从诺基亚文档工作正常。

I'm trying to send a sms via a Nokia phone over serial which is easy enough via putty. The commands from the nokia documentation works fine.

不过，试图从C＃应用程序发送相同的命令惨遭失败。我已经运行的Sysinternals PortMon，可以查看相应的命令来通过OK，我能看到的唯一的区别是它的方式连接，但我无法找到这将化解这些分歧的命令。

However, trying to send the same commands from a c# application fails miserably. I've run Sysinternals PortMon and can see the commands come through OK, the only difference I can see is in the way it connects but I am having trouble finding the commands that would iron out those differences.

我跑的代码看起来有点像这样

The code I'm running looks a little bit like this

using (SerialPort port = new SerialPort(comPort, 9600, Parity.None, 8, StopBits.One))
    		{
    			port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived);
    			port.ErrorReceived += new SerialErrorReceivedEventHandler(port_ErrorReceived);

    			//port.ReceivedBytesThreshold = 1;
    			port.DtrEnable = true;
    			port.RtsEnable = true;
    			port.ReadTimeout = 1;
    			port.Handshake = Handshake.XOnXOff;


    			try
    			{
    				port.Open();

    				port.WriteLine("AT");

    				port.WriteLine("AT+CMGF=1");

    				port.WriteLine("AT+CMGS=\"" + number + "\"");

    				port.WriteLine(message);

    				port.Write(new byte[] { (byte)26 }, 0, 1);
    			}
    			finally
    			{
    				if (port.IsOpen)
    				{
    					port.Close();
    				}
    			}

我在跟踪从看到的差异串行端口的

The differences I'm seeing in the trace from the serial port are

在启动

0.00001844  aspnet_wp.exe	IOCTL_SERIAL_SET_HANDFLOW	USBSER001	SUCCESS	Shake:1 Replace:43 XonLimit:4096 XoffLimit:4096

和在最后

0.00061153  aspnet_wp.exe	IOCTL_SERIAL_PURGE	USBSER001	SUCCESS	Purge: RXABORT RXCLEAR	
0.00004442  aspnet_wp.exe	IOCTL_SERIAL_PURGE	USBSER001	SUCCESS	Purge: TXABORT TXCLEAR

有没有人有关于如何化解这些问题的任何提示？我也注意到，当我发出一个命令，所以我怀疑问题是与连接，最后不是那些信息的电话未与任何确认响应返回给应用程序。

Has anyone got any tips on how to iron out these issues? I also notice that the phone is not responding back to the application with any acknowledgement when I issue a command so I suspect the problem is with the connection, not those messages at the end.

推荐答案

您需要等待>写出了消息之前。另外，不要终止与CR / LF（的WriteLine）消息。

You need to wait for the ">" before writing out the message. Also, don't terminate the message with a CR/LF (WriteLine).
