BIR Bus Interface Register

We can solve these problems effectively by reforming the hardware of the serial port or directly write a program for the interface register of 8250.

访问串行口可以有多种方法,可以用DOS功能调用,也可以用BIOS功能调用,但是DOS功能调用和BIOS功能调用在实际应用中存在一些问题,通过对串行口的硬件进行改造或直接对8250内部的接口寄存器编程,可以比较好地解决此类问题,在实际应用中能取得良好的效果,对于除了串行口接MODEM以外的其它应用,这种方法都是有效的。

The method to achieve circuit of A16/D16 register-based interface is put forward, the softpanel and drivers to apparatus are developed.

系统设计了A16/D16寄存器基接口电路,开发了软面板和仪器驱动程序。
