实现串口的通信功能-Serial communication function

一个用delphi写的端口的监控程序。（搜集的，不是本人的）-a supervising program for port based on Delphi.(collecting,not by myself)

自己用API编写的端口通讯-Port Communication with API by myself

C51写的单片机串口通信程序,用于键盘测试和USB接口测试!-C51 microcontroller serial communication procedures for testing and USB keyboard interface test!

This is the free RTOS on PIC24.

用VC++实现的串口通信，使用mscomm控件，经过实际工程使用测试过，包括发送和接收两块，希望对大家有所帮助-With VC++ Realize the serial communication, use the MSComm control, after the actual use of the test works, including sending and receiving two, and they hope to help everyone

avr atmega8的查询方式的串口通信-avr atmega8 of ways to search for serial communication

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.

实现函数发生器产生的波形能够在电脑显示器上显示。函数发生器通过GPIB卡与电脑连接并传输数据，电脑上通过LABVIEW软件环境完成与GPIB卡的数据通信。在LABVIEW环境下完成了对虚拟仪器前面板以及后台程序框图的设计与编程。在LABVIEW开发环境下，实现对GPIB控制时，采用VISA模块驱动的方法进行编程。设计结果在LABVIEW环境下的虚拟示波器能够实现示波器的功能，能够显示函数发生器所产生的任意波形。- achieve the waveform can be displayed on the screen of the computer which send out by the function generator. The function generator connect to computer through a GPIB card and transfer data. Labview can be communicated with GPIB card and save data on computer. The virtual instrument front panel design and background process diagram programming can achieved under Labview software environment. The realization of GPIB control, using VISA module-driven approach to program in Labview. The result of the design is that the virtual oscilloscope is able to complete the Real oscilloscope function in Labview.
