编程:串行口调试程序-Programming : serial port debugger

VB 5.0/6.0的MSComm通信控件提供了一系列标准通信命令的接 口，它允许建立串口连接，可以连接到其他通信设备（如Modem）、 还可以发送命令、进行数据交换以及监视和响应在通信过程中可能 发生的各种错误和事件，从而可以用它创建全双工的、事件驱动 的、高效实用的通信程序。-VB 5.0/6.0 the MSComm control communications for a series of standard communication interface orders, which allow for the establishment of serial link can be connected to other communications equipment (such as modem), and also can send orders, the exchange of information and surveillance and response in the communication process may mistakes that occurred in the incident, which can be used to create full-duplex, event-driven, highly effective and practical communication program.

串行口测试程序。例如：程序复位后先向串口发送"Hellow Word!",之后每从串口收到一个字符就把它从串口发送出去 -serial testing procedures. For example : After the first reduction procedures Serial send "Hellow Word!" , After each received from the serial port of a character out of it sent from the serial port

Windows 2000 环境下直接访问串口、并口的小程序，包括VC、delphi源码-under Windows 2000 directly to the serial port, parallel port of small programs, including the VC, Delphi source

这是一个基于TCP/IP协议的通行应用调试程序，希望对大家有所帮助-This is based on TCP/IP protocol of the current application debugger, I hope all of you to help

串口ROM编程,内部包括了I2C总线的许多内容,启动总线,结束总线-Serial ROM programming, including the internal I2C Bus many elements, initiated bus, the end of bus

自己写的一个串口类,从CNCOMM改正过来的,精简代码,解决了只能事件方式下只能接收几个字符的问题-Himself wrote a serial type, from CNCOMM mistakes, to streamline the code, solve the incident only way to receive only a few characters in the issue of
