与串口通讯 [英] Communicating with serial port

问题描述

我是使用C ++的中级程序员.我目前有一个通过并行端口控制步进电机的程序，但是我希望在上面执行代码的笔记本电脑只有一个串行端口.

我猜想您不能只是购买用于串行->并行的适配器并以这种方式运行代码?

我听说串行端口的握手线可能是一个不错的选择，但是还没有弄清楚如何在编码中访问它们.

非常感谢您的帮助，

I am an intermediate programmer using C++. I currently have a program to control a stepper motor through a parallel port, but the laptop that I wish to execute my code on only has a serial port.

I am guessing you cannot just buy an adapter for serial->parallel and run the code that way?

I have heard that the handshaking lines of the serial port could be a good option, but have not figured out how to access them in the coding.

Thank you very much for your help,

推荐答案

您也将错了:

如果您要使用的是V +，并且您正在使用Windows，请通过

if all you want is V+ and you''re using Windows, have a look at using the DTR line thru EscapeCommFunction[^]
