推荐答案

访问客户机从Web应用程序开始并不容易。 大多数浏览器提供对其中运行的应用程序的有限访问，以避免安全问题。 ActiveX可以允许访问com端口，但activex本身需要用户的权限。 Accessing client machine from a web application is not easy. Most browsers provide limited access to the applications running inside them to avoid security issues. ActiveX could allows access to the com port but activex itself requires permissions from the user.
