问题描述
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/古老的 VC6 代码.
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.
推荐答案
为了与串行端口连接，您需要打开一个文件名为COM1"到COM9"的特殊文件名之一.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
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.
http://msdn.microsoft.com/en-us/library/ms810467.aspx 有一个关于使用串行端口.请注意，您应该使用 Windows 文件 I/O 函数，例如 CreateFile()、ReadFile() 和 WriteFile().我不确定使用标准 I/O 函数(例如 fopen()、fread() 和 fwrite() 是否可行)>.
http://msdn.microsoft.com/en-us/library/ms810467.aspx has 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().
