一个外国人写的rs485串口通信程序，有原理图和源代码，全面实现了485协议...

一个串口测试程序，包括源代码，供大家学习-A serial test procedure, including the source code for the U.S. study

将串口通讯协议存储为一个通讯文件，可是随时将存储通讯协议文件调入计算机运行与下位机通讯可以实现通讯对话，-Serial communication protocol will be stored as a communications document, but to keep the communication protocol storage document transferred to the computer is running and the next-bit machine communication can realize communication dialogue

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

串行通信的（源代码）做maxplusII

VB MODBUS资料，用vb传输串口通信的例子 -VB MODBUS example

是一个用VB编写的OPC客户端数据采集程序，在工业控制上经常会用到该通讯方式

这是一个串口通信的实例。 里面用到很多控件，对于初学者值得学习！-This is an example of serial communication. Which used a lot of control, for beginners to learn!

自己编写的计算机与单片机通讯时，下位机的模拟系统-I have written single-chip computer and communications, the next bit machine simulation system

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
