用来模拟PC机的串口，实现各种串口数据读写的功能！

51单片机作为主站的MODBUS通信协议，可实现读写从站寄存器的值 -51 MCU as the main station MODBUS communication protocol can realize the value of register read and write from the point

从串口读取，并解析NMEA格式的GPS数据的程序。将解析后的数据显示到界面上。需要和发送端的程序配合使用。-read from the serial port and analytic NMEA GPS data formats procedures. Analysis of the data shows that the interface. Needs and transmitter used in conjunction with the procedure.

通过串口与IC设备进行数据交互传输，实现IC卡餐饮收费系统。-through the serial port and IC equipment interactive data transmission, Food IC card system.

Dos下串口通讯编程-Serial Communication Program

本人用vc++编的关于串口通信的小程序，可以在2台PC之间互通数据-I used vc++ Made on the serial communication of a small program, you can share between 2 PC data

This program I use to tested serial com and AT Command for testing GPRS for SIM300 GSM module

一个好用的串口调试软件，不下载可惜了，方便你的工程开发-An easy to use serial port debugging software, not to download Unfortunately, and to facilitate the development of your project
