USB2.0标准协议,是嵌入式系统工程师必备通信协议

优盘进行串口通信源代码,需要的下了-USB to serial communication source code, need a

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.

串口RS232与PIC16F877A单片机通信.用于控制PIC单片机产生音乐,附完整报告.-RS232 serial communication with the PIC16F877A Singlechip. Singlechip produce PIC is used to control music, a complete report is attached.

对要进行网络编程和串口编程的人员有很大帮助。-right to network programming and serial programming staff is very helpful.

使用vb.net实现串口通讯的过程，具体见程序。谢谢！-vb.net using Serial communication process, see the specific procedures. Thank you!
