摘要
使用TL16C554、单片机等设计制作了通用微机串口扩展器。可以实现一台微机同最多八台微机间的串行通信。采用了时隙法和标志法两种方法进行程序设计,使用了超时中断和环形队列,使此扩展器具有通用性和一定的应用价值。
An interface box of tmiversal PC serial port has been designed and made by using TL16C554 and MCU, which can realize commtmication between one PC with eight PCs. Two methods are used in the design： timeslots method and marks method. Its program also uses overtime interrupt and circle queue, which make the interface box more tmiversal and has more value for applications.
