介绍有关IBM-PC微型计算机间异步串行通讯的软硬件特性,并给出高速全双工异步通讯的设计方法和实现途径。应用本方法可在不改变硬件结构的前提下实现高达115,200bps的波特率,且不增大误码率。
Describes the hardware and software features of asynchronous serial communication between IBM-PC microcomputers, and gives the design method and realization of high-speed full-duplex asynchronous communication. With this method, baud rates up to 115,200 bps can be achieved without changing the hardware structure without increasing the bit error rate.
