客户端使用IOCTL_SERIAL_WAIT_ON_MASK请求来等待等待事件的出现。 如果在处理 set-wait-mask 请求时已挂起等待掩码请求,则挂起的事件等待请求的状态为STATUS_SUCCESS并且输出等待事件掩码设置为零。 主要代码 IRP_MJ_DEVICE_CONTROL 输入缓冲区 AssociatedIrp.SystemBuffer成员指向客户端分配并设置为事件等待掩码的 U...
The IOCTL_SERIAL_SET_WAIT_MASK request configures the serial controller driver to notify a client after the occurrence of any one of a specified set of wait events.

This IOCTL sets the value of the wait mask. Parameters dwOpenData [in] Specifies the handle returned from a call to the COM_Open function. dwCode [in] Specifies this code. pBufIn [in] Pointer to a DWORD that contains the event mask set by SetCommMask. dwLenIn [in] Specifies the size...
IOCTL_SERIAL_SET_BREAK_OFF:停止发送BREAK信号。 IOCTL_SERIAL_SET_WAIT_MASK:设置等待面具。 IOCTL_SERIAL_WAIT_ON_MASK:等待指定的事件。 IOCTL_SERIAL_SET_CHAR:设置特定的字符。 IOCTL_SERIAL_GET_CHAR:获取特定的字符。 IOCTL_SERIAL_SET_TIMEOUTS:设置超时参数。

IOCTL_SERIAL_SET_WAIT_MASK 是要过滤的消息类型的包含列表。 那么,有三个问题: 呼叫者ID信息是否可能被 IOCTL_SERIAL_SET_WAIT_MASK 抑制? 如果是这样,我如何配置它以显示来电显示信息?它似乎无法从类属性访问。 如果我无法配置它,我唯一的选择是绕过它来编写我自己的包装器来控制串口的低级系统功能? 我对串口...

The returned mask shows the event that terminated the wait. If a process attempts to change the device handle's event mask by using the IOCTL_SERIAL_SET_WAIT_MASK call, the driver should return immediately with (DWORD)0 as the returned event mask. ...
