Transporting DNP V3.00 over Local and Wide Area Network. 1 Overview 1.1 Purpose DNP V3.00 (hereafter referred to simply as DNP) was designed for serial point-to-point communication (e.g. RS-232) with limited support for half duplex serial networks (e.g. RS-485). In order for devices to exchange DNP messages in a local (LAN) and/or wide area network (WAN), one must either augment the protocol to support a network environment or use an existing network transport mechanism. This document takes the latter approach specifically, to define how to transport DNP traffic on the internet protocol suite. -Transporting DNP V3.00 over Local and Wide Area Network. 1 Overview 1.1 Purpose DNP V3.00 (hereafter referred to simply as DNP) was designed for serial point-to-point communication (e.g. RS-232) with limited support for half duplex serial networks (e.g. RS-485).

本代码为MSComm控件在VC的MFC程序中控制多个串口的应用实例。在使用MSComm控件时，1个MSComm控件只能同时对应一个串口。如果应用程序需要访问多个串口，那么必须使用多个MSComm控件。-MSComm control of the code for the MFC in VC process control multiple serial application. In the use of MSComm control when a MSComm control only at the same time corresponds to a serial port. If an application needs to access multiple serial port, then must use a number of MSComm control.
