C#.net中的串行端口 [英] Serial Ports in C#.net

问题描述

人们.
我正在开发一些设备自动化应用程序，需要通过串行pport和RS232接口连接到该设备，并将ASCII数据发送和接收到端口.我已经使用了一些像这样的代码:

Hi people.
I''m working on some device automation application and need to connect to it via a serial pport and a RS232 interface and send and recieve ASCII data to the port. I''ve used some codes like this:

SerialPort srp = new SerialPort("COM2", 19200, Parity.None, 8, StopBits.One);

srp.Open();
srp.WriteLine("some commands");
srp.Close();

我的设备对此代码不采取任何措施，但是我对命令语法有把握.我的二手代码中有问题吗?有人可以帮我吗?

My device takes no action with this code but I''m sure about the command syntax. Is the problem in my used code? Could anyone help me please?

推荐答案

当您使用writeLine方法将指定的字符串和NewLine值写入输出缓冲区时.新行可能是问题所在.您可以验证一下.

Hi,

When you use writeLine Method that writes the specified string and the NewLine value to the output buffer. The New line is maybe the problem. You can verify this.

嗨
您的代码似乎正确吗?
您可以下载任何虚拟串行端口仿真器.配对任何两个虚拟端口，并让您的应用程序与任何已配对的端口连接.将消息发送到同一端口，您将可以使用Microsoft超级终端侦听其他端口(或者您可以创建自己的应用程序以侦听并将消息发送到端口).如果正确获取消息，则代码中没有问题.可能是分隔符是问题所在.

希望这会帮助你.

Hi
Your code seems right?
You can download any virtual Serial port emulator . Pair any two virtual port and let your application connect with any port ,just paired. Send the message to the same port , you will can listen to other port using the Microsoft hyper terminal ( or you can create your own app to listen and send message to a port). If you are getting the message properly ,then there is no issues in your code . May be the delimiter is the issue.

hope this will help you.

我不是专家，但是您尝试过吗?

I am not an expert but have you tried this?

SerialPort srp = new SerialPort("COM2", 19200, Parity.None, 8, StopBits.One);
srp.Open();
srp.WriteLine("some commands"+Environment.NewLine);
srp.Close();
