利用8088/86CPU控制8251A可编程串行通信控制器，实现两个实验台之间的串行通讯。其中一个实验台作为发送方，另一侧为接收方。发送方读入按键值，并发送给接收方，接收方收到数据后在LED上显示。-Use 8088/86CPU control 8251A Programmable serial communication controller, to achieve two experiments serial communication between China and Taiwan. One of the bench as the sender, the other side of the receiver. Read key value of the sender, and send it to the receiver, the receiver data received after the LED display.
