本实验实现PS/2接口与RS-232接口的数据传输， PS/2键盘上按下按键，可以通过RS-232自动传送到主机的串口调试终端上（sscom32.exe）； 并在数据接收区显示接收到的字符。 串口调试终端的设置：波特率115200，一个停止位，无校验位。 -Realize this experiment, PS/2 interface with RS-232 data interface, PS/2 keyboard to press the button, through RS-232 automatic transmission to the host serial debug terminal (sscom32.exe) and data receiving display received characters. Serial debug terminal settings: 115200 baud rate, one stop bit, no parity bit.
