使用C++实现将Modbus协议封装在DLL中的源代码

GSerial是一个DOS下串口通信程序，程序结构较好，能编出用中断方式接收/发送的多串口通信程序（龚建伟曾用它编过7串口通信程序）。Turbo C++ 3.0 Dos或 Win3X/9X/ME/NT/2K的DOS环境下运行-GSerial under DOS is a serial communication program, program structure better, can be compiled out with interrupt receiving/sending of multiple serial communication program (Dan has used its seven series serial communication procedures). Turbo C 3.0 Dos Win3X/9X/ME/NT/2K or the DOS operating environment

将串口通讯协议存储为一个通讯文件，可是随时将存储通讯协议文件调入计算机运行与下位机通讯可以实现通讯对话，-Serial communication protocol will be stored as a communications document, but to keep the communication protocol storage document transferred to the computer is running and the next-bit machine communication can realize communication dialogue

UART测试代码，可以与实现下位机与上位机之间的RS232协议的UART通信测试-UART test code, can achieve the lower computer and the host computer RS232 protocol between the UART communications test
