Hi expert, I failed to use 16550 Compatible Uart to send data. Serial signal never change. I have write the configure to the register: 0x4 to 0x0;
開啟和初始化 16550 UART-Compatible 介面 當Serial 作為較低層級的裝置篩選驅動程式使用時,下列考慮適用于開啟和初始化篩選裝置: 序列在篩選裝置上一次只支援一個開啟。 篩選裝置在開啟時處於未定義的狀態。 用戶端應該先將篩選裝置初始化為已知狀態,再使用它。 使用者模式用戶端可以使用IOCTL...
