SPcomm控件源代码,delphi写的!! 有兴趣的可以研究一下!

一个通用的串口通讯类，可以作为串口编程的学习之用-a universal serial communications can be used as serial programming with Learning

用于VC的DLL库，使用异步通讯方式，具体使用方法请看源码-for VC DLL libraries, the use of asynchronous communication and the use of specific methods Look at source

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.

串口操作源程序，可以对串口读写操作，当然也可以自发自收，是一个联系串口通信的好例子-source can write to serial port, of course, can also spontaneously collected, the serial link is a good example of communication

用于串口应用程序的调试监控工具，软件可模拟设备往串口发送指定格式的数据串，同时也可以用于实时监控串口读写过程中的所有数据流。☆ 自动侦测当前系统中所有可用的串口数，支持USB扩展出的虚拟串口（可到COM256）。☆ 支持ASCII码和十六进制数据格式的发送和接收。☆ 可以自由选择侦测的串口，接收数据区的容量可以无限大。☆ 发送、接收数据区的大小可以随意拉伸调节。☆ 对发送、接收数据区加入鼠标右键菜单的支持。☆ 扩大串口波特率的支持，现最高Baud可到921600。☆ 支持Unicode内码显示。☆ 增加自动发送数据功能。☆ 增加保存显示记录的功能。-applications for serial monitoring of debugging tools, software can simulate serial devices to send data to the specified format string, but also can be used for real-time monitoring serial process of reading and writing all data stream. automatically detect the current system all available serial number, support USB expansion of Virtual Serial Port (available to COM256). support ASCII and hexadecimal format of the data to send and receive. freedom of choice to detect the serial and receive data in large capacity can be unlimited. send and receive data of arbitrary size can adjust tension. right to send and receive data by adding areas of the right mouse button menu support. serial port baud rate of expansion, is
