串口测试程序。-Vl Series single-chip computer and communications systems are generally run by a PC computer software, a serial cable and the next-bit machine that is composed of single-chip target board in this way to learn and debug serial communication procedures麻烦. This article describes the realization of a computer with Proteus and single-chip serial communication method of simulation, all things are completed on a computer. PC software and the next-bit machine that is AT89C51 single-chip circuit simulation software through a virtual serial port Virtual Serial Ports XP5.1 generated virtual serial port to connect the two. Examples of articles in the use of PC serial port debugging software assistant. The next software is written by the author of a serial test procedure.
