Question

这是可能的吗? 如果是的话,工业标准在软件上如何? 具体地说,我指的是蚊帐控制。

谢谢。

EDITED: Here is what I need. I have a thin client with a balance where RS-232 is used to interact with the thin client. Currently, it is a compact framework app. What I would like to know id whether it is possible to have the same set up in a web application. So that would entail that the RS-232 is NOT the server RS-232 - it is the user s computer RS-232 - RS-232 is on the client. So when the RS-232 spits out input, it should go to the browser. Is it possible in a web application?

Answer 1

我可以考虑两种方式;

Buffer the serial data in an application object, and then use an ajax call triggered by a timer to grab and display the latest data.
对于数据流的较短,你可以不使用p.net控制本身,而是采取类似做法;
```
Response.ContentType = "text/plain";
Response.Clear();

String serialData;

while(serialData = getSerialData() {
   Response.Write(serialData);
   Response.Flush();
}
```
这将实时向网络浏览器撰写文字内容。也许你不想让本届会议保持太长时间。

如果你想在另一页内显示数据流,那么该页与上述代码放在一栏。

还指出,上述工作最好用的是作为手提的手提,而不是像头。

Answer 2

当然,你可以这样做。页: 1 System.IO. Ports.Serial Port instance, andproduct it through a HttpListener 。

骗局将知道你想要与<代码”这一页做什么。 HttpListener上台。由于数据将实时输入COM港,你很可能想在吉大港山区向您的服务器提出请求之间加以缓冲,因为否则,如果你试图在没有数据等待的情况下阅读港口,你就把听器hang。如果你不定期阅读数据,填写<代码>Serial Port为缓冲。
