IOCTL_SERIAL_SET_LINE_CONTROL请求 (LCR) 设置行控制寄存器。 行控件寄存器控制数据大小、停止位数和奇偶校验。
1.IOCTL_SERIAL_SET_LINE_CONTROL和IOCTL_SERIAL_GET_LINE_CONTROL IOCTL_SERIAL_SET_LINE_CONTROL和IOCTL_SERIAL_GET_LINE_CONTROL是两个IOCTL命令代码,用于设置和获取串口的行控制参数。这些参数包括停止位、数据位和奇偶校验位。 1.1SERIAL_LINE_CONTROL结构体 这两个IOCTL命令都使用SERIAL_LINE_CONTROL结构体来传递...
TheIOCTL_SERIAL_SET_BREAK_OFFrequest sets the line control break signal inactive. To set the line control break signal active, a client can use anIOCTL_SERIAL_SET_BREAK_ONrequest. Major code IRP_MJ_DEVICE_CONTROL Input buffer None.
