接收数据的COM端口通知 [英] COM Port notification for Receiving Data

问题描述

我需要知道COM端口是否有任何通知可用来指示数据到达. ]
现在我处于一个SMS项目中，我需要在收到SMS时阅读该消息.
我正在使用AT命令"AT + CNMI"，因此我的调制解调器将读取新收到的SMS，并将信息发送到COM端口.
我正在使用线程读取COM端口数据.我需要启动线程，但是我不知道如何通知我的线程COM端口中的数据可用.

如果您知道，请告诉我我快到期限了

在此先感谢

作为一种简单的方法，您的读取线程可能只是在ReadFile操作上被阻塞而等待.

As simple approach, your reading thread may simply wait, blocked on a ReadFile operation.
