51单片机串口调试程序，谢谢大家使用，本人刚出道，希望大家多多包涵-51 microcontroller serial debugging procedures, thank you all use, the title track, I hope you will forgive me

串口通信程序，使用COM1串口进行计算机通信的软件-Serial communication program, use the COM1 serial port for computer communications software

UART接口的VERILOG代码，经过调试成功！-UART interface Verilog code, after the successful commissioning!

串口测试程序，打开，写数据，受数据，关闭-serial testing procedures to open and write data by the data, closing

我用VC编的一个小小的串口应用程序,里面用到了一个库CComm。挺简单的。-I VC series a tiny serial applications, they use a library CComm. Very simple.

本人调试通过的串口通信程序,对初学者有一定的参考价值-I debugging through the serial communication program for beginners with some reference value

本串行通信程序利用汇编语言通过BIOS中断调用和DOS功能调用实现PC机双机串行通信。其中，上位机和下位机串行口均为辅串口COM2（口地址为2FXH），对外用9针连接器与令一台PC机连接；BIOS通过“INT 14H”4个中断服务子程序，分别完成串口初始化编程、发送一帧数据、接受一帧数据以及测试通信线状态。本程序分为PC机串口自动测试程序（目的是测试串口好坏）和PC机全双工双机通信程序两个部分。-the serial communications procedures through the use of assembly language BIOS interrupt calls and function calls DOS PC Dual Serial Communication. Among them, PC and the next crew will be supplemented by serial port Serial COM2 (I address 2FXH) external with 9-pin connectors and enable a PC connection; through the BIOS "INT 14H," four interrupt service routines, complete serial port initialization programming, Send a data receiving a data communications test and the state line. The procedures are divided into PC serial automatic test procedure (for the purpose of testing Serial good or bad) and full-duplex PC-machine communication program two parts.
