多谢，大本营的对我的帮助。这是一个串口调试程序，供大家参考。

serial.h serial.cpp 共两个文件，VC串口封装API类-serial.h serial.cpp a total of two documents, VC serial API Class Packaging

对LINUX下IC卡读写操作函数，用的是明华公司的读卡器-right LINUX IC card reader manipulation functions, the Chinese company is out of the reader

详细介绍了使用VB编制串口通信程序，其中包含循环冗余校验CRC代码段-Described in detail the preparation of the use of VB serial communication program, which includes cyclic redundancy check CRC code segment

用vb实现串口间通信,可以用来熟悉串口间传输信息的原理.-with Serial Communication, which can be used with serial transmission of information between the principle.

串口演示源程序合集，三个程序BCB5_COM 是在BCB5下使用的例子，Console 是在控制台中使用的例子，VC_ComDlg 是在对话框中使用的例子-Serial Collection demonstration source, the three procedures in BCB5 BCB5_COM use examples, Console is used in the console example, the dialog VC_ComDlg used in the example

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。-Note : This only source for information, some not function prototype reference in its communications and its settings. CRC calibration can be a reference to the other code.
