EvtChar Specifies the value of the character used to cause the EV_RXFLAG event. This setting does not actually cause anything to happen without the use of EV_RXFLAG in the SetCommMask function and the use of WaitCommEvent. wReserved1 Reserved; do not use. Flow...
EV_RXFLAG接收到事件字符(DCB结构的EvtChar成员),并放入输入缓冲区 EV_TXEMPTY输出缓冲区中最后一个字符发送出去 ==1. 操作通信事件== 应用程序可以通过SetCommMask()函数建立事件掩模来监视指定通信资源上的事件。SetCommMask()函数的声明如下: BOOLSetCommMask( HANDLE hFile, DWORD dwEvtMask ); ...
