Basic example of serial communication with Windows XP/win32
提问by
I am working with a peripheral device that needs to be communicated through serial. I can send it commands using HyperTerminal, but now I need to write programs that will let me do it without HyperTerminal. Can somebody point me to a website and/or show me a sample hello world program to get me started? I have searched through many sites which give me uncompilable/ancient VC6 code.
我正在使用需要通过串行通信的外围设备。我可以使用超级终端向它发送命令，但现在我需要编写程序，让我在没有超级终端的情况下也能做到。有人可以将我指向一个网站和/或向我展示一个示例 hello world 程序以帮助我入门吗？我搜索了许多网站，这些网站提供了无法编译的/古老的 VC6 代码。

In order to interface with the serial port, you open a file with one of the special filenames "COM1" through "COM9". For serial ports with higher numbers, the special filename begins with \\?\, which in C/C++ code must be escaped as "\\\\?\\COM10", etc.
为了与串行端口接口，您打开一个文件，其中一个特殊文件名是“COM1”到“COM9”。对于数字较大的串口，特殊文件名以 \\?\ 开头，在 C/C++ 代码中必须转义为“\\\\?\\COM10”等。
http://msdn.microsoft.com/en-us/library/ms810467.aspxhas a really good tutorial on using the serial port. Note that you should use the Windows file I/O functions such as CreateFile(), ReadFile(), and WriteFile(). I'm not sure if it will work to use standard I/O functions such as fopen(), fread(), and fwrite().
http://msdn.microsoft.com/en-us/library/ms810467.aspx有一个关于使用串口的非常好的教程。请注意，您应该使用Windows文件I / O功能，如CreateFile()，ReadFile()和WriteFile()。我不知道是否会工作到使用标准I / O功能，如fopen()，fread()和fwrite()。

Microsoft provides an article with sample codedescribing how to do this under Win32.
Microsoft 提供了一篇文章，其中包含描述如何在 Win32 下执行此操作的示例代码。

Boost:asiomay be able to help as a serial device was added recently.
Boost:asio可能会有所帮助，因为最近添加了串行设备。
Fair warning though; the serial port documentation is light, presumably since it's quite new (it was added in asio 1.1.1 which was included in boost 1.36).
公平的警告；串口文档是轻，大概是因为这是相当新的（它是在ASIO 1.1.1其中包括在提升1.36加）。
But working your way through asio is, IMHO, a better solution than using the raw Win32 API. Why? It'll be easier to read and maintain (it's a higher level API) and it'll be cross platform (except where you need to specify the OS-specific device name).
但是，恕我直言，通过 asio 工作是比使用原始 Win32 API 更好的解决方案。为什么？它将更易于阅读和维护（它是一个更高级别的 API）并且它将是跨平台的（除非您需要指定特定于操作系统的设备名称）。
The Boost - Usersand asio.usermailing lists are quite active and friendly and ought to be able to help you out if you get stuck.
The Boost - Users和asio.user邮件列表非常活跃和友好，如果您遇到困难，应该能够帮助您。

If using .NET 2.0 see System.IO.Ports and this articleshould be helpful. If direct Win32, then Adam's answeris best.
如果使用 .NET 2.0，请参阅 System.IO.Ports，这篇文章应该会有所帮助。如果直接使用 Win32，那么Adam 的答案是最好的。

I believe you will find plenty of sample code for C# as well if you find VC6 too ancient. I think there are also a bunch of "free" serial/COM port wrappers but I just wrote my own when I wrote an RS232 device controller piece of software.
如果您发现 VC6 太古老，我相信您也会找到大量的 C# 示例代码。我认为还有一堆“免费”串行/COM 端口包装器，但我在编写 RS232 设备控制器软件时只是编写了自己的。
google C# and serial port or rs232
谷歌 C# 和串口或 rs232
I got these:

You should have no problem finding suitable code with a google search.
使用谷歌搜索找到合适的代码应该没有问题。
