一个全球定位系统和串口通信程序，很好的信息给一个全球定位系统的信号…

串口编程（中文翻译版）----绝对经典书籍

用来模拟PC机的串口，实现各种串口数据读写的功能！-used to simulate the PC serial port, serial data of various functional literacy!

The EZ320 utility demonstrates the communication program between host PC and the MR320.

简单的串口通信程序!通过按键来实验是否将主机中相应缓冲区中的内容传送给从机!主机状态改变,按键传输时,从机状态也将改变!-Simple serial communication program! Through the keys to the experiment whether or not to host the corresponding buffer content transmitted to the slave! Host state changes, button transmission, from the state machine will change!

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.

用于实现上位机与下位机通信功能。用于串口通信。-For implementation with the lower PC communication function. For serial communication.

RCC底层通信程序 包含协议和测试报告-RCC SerialPort

用于在线仪表的 modbus,仅供参考，-online instrument for modbus connection, for information purposes only, thank you

基于串口的一个小程序,可以用来接收和发送短信消息-a progress of serial port you can use it send and receive messages

通过USB接口利用多媒体进行数据采集的源程序，通过调试的。-through the USB interface for multimedia data acquisition of the source, through the debugger.
