使用vb.net实现串口通讯的过程，具体见程序。谢谢！

和基本使用BCB控制RS-232信号控制测试的源代码，初学者推荐

本软件在C++ Builder 6.0开发环境下编程，实现的功能是：如果将本机的两个串口通讯口COM1和COM2连接起来，可以实现本机内这两个COM口间的数据的传输；若将两台电脑的COM口连接起来，可以实现这两台电脑的串行数据传输。-the software in C Builder 6.0 development environment programming, the functions are : If the machine two serial communication port COM1 and COM2 link up the machine can achieve this within two COM ports of data transmission; if two computers connected to the COM port, This can be achieved two computer serial data transfer.

我用vb编写modbus协议,拿出来与大家分享一下，厚厚，希望得到大家的指教-Modbus protocol prepared hard to share with you some thick hope to enlighten all

一个串口通信的软件，需要spcomm组件，请注意-a serial communication software, the need spcomm components, please note

串口通信例程，内含串口类，一个老外写的，我修正了一个bug：在接收数据流未完成前退出程序会导致进程驻留在内存-Serial communication routines, containing serial port class, written by a foreigner, I fixed a bug: the receiving data stream does not quit the program before the completion of the process will lead to reside in memory

串口编程源代码,从别处转载的,有一定参考价值!-serial programming source code, reprinted from elsewhere, a certain reference value!

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.

此源代码是一个很复杂的串口通信的例子，序，可以运行。-this source code is a very complicated serial communication example, sequence, can run.

编写串口通信程序，可以不同的格式传输，可以自动发送和手动发送。-prepared serial communication procedures, different transmission formats, it will automatically send and sent manually.

该程序演示了如何在windows平台下使用WindowsAPI函数来操作串口，可以用以实现两台PC机之间的实时聊天。（必须连接串口电缆）-the program demonstrated how the Windows platform using Windows API function to operate serial ports, can be used to achieve between two PC real-time chat. (Must connect serial cable)
