手机端与电脑实现串口通信，在VC环境下编程，包含源程序-Mobile terminal with a computer serial communication programming in the VC environment, including source code

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.

基于CSerialPort串口类的的出口通信，比用串口通信控件更方便。-Based on the export of the class CSerialPort serial communications, serial communication control than with more convenient.

双机串行通讯源程序(汇编),文件关联可以修改,默认为DXP2004-Dual Serial Communication source (compilation), file association can be amended, by default DXP2004

自己使用VB编写的串口通信程序，1号和2号。将两个COM口用串口线连接，就可以运行这两个程序了。实现的功能：1号程序随机发送两个数字，2号程序接收并进行计算，然后发回1号机，1号机接收并显示出来。-its own use VB prepared by the serial communication program, 1 and 2. The two COM ports with serial line connectivity, it can run on the two proceedings. The functions : 1 random procedure to send two figures, the No. 2 receiver and procedures for calculating and then sent back No. 1, No. 1 receiver and displayed.

W77E58双串口通信源代码 注：此源程序只作参考，内有些函数未有原型，借鉴在于其通信方式及其设置。 CRC检校可另参考其它代码。 -W77E58 dual serial communication source code Note : This program is for reference only, not some function prototype experiences in his means of communication and set up. CRC calibration can be a reference to other codes.
