vb demonstration of various communications functions Mscomm

的问题.派尔高协议,控制左转右转时,出现问题.其他功能好用.我用DELPHI写的程序,在MOUSEDOWN中, str := chr($FF)+chr($01)+chr($00)+chr($04)+chr($0F)+chr($00)+chr($14) MSComm1.output := str 在CLICK事件中: str := chr($FF)+chr($01)+chr($00)+chr($00)+chr($00)+chr($00)+chr($01) MSComm1.output := str -Problem. Pelco agreement左转右转control when there are problems. Other features easy to use. DELPHI I used to write the procedures in the MouseDown, str: = chr ($ FF)+ Chr ($ 01)+ chr ($ 00)+ chr ($ 04)+ chr ($ 0F)+ chr ($ 00)+ chr ($ 14) MSComm1.output: = str in the CLICK event: str: = chr ($ FF)+ chr ($ 01)+ chr ($ 00)+ chr ($ 00)+ chr ($ 00)+ chr ($ 00)+ chr ($ 01) MSComm1.output: = str

此程序利用串口读取民航AFTN电报网中的AFTN信息，然后进行电报解读，并将解读出来的信息存储到数据库中。是民航常用的电报数据读取端口-use of this procedure to read CAD AFTN serial cable network AFTN the information and then proceed telegram read, and read out the stored information to the database. CAD is used to read the data cable port

串口通信控制XX变频器,VB下编的界面，已调试通过，可以运行，-VB_rs232_transducer

一个VB语言编写的，用计算机COM口进行数据传输的程序。-a VB language, computer COM port for data transfer procedures.

一个用8255的串口编程-8255 with a Serial Programming

PL2303 driver , usb to serial driver for mobile phones

和基本使用BCB控制RS-232信号控制测试的源代码，初学者推荐

利用MSComm控件，不依赖太多硬件设备，指利用纯软件方法侦测串口通信参数设置情况-use MSComm control, do not rely on too many hardware devices that use software-only method to detect serial communication parameters settings

使用vb.net实现串口通讯的过程，具体见程序。谢谢！-vb.net using Serial communication process, see the specific procedures. Thank you!

一个dll演示代码 用于串口通信的。 类似于工控的驱动-Dll demo code for a serial communication. Similar to industrial drive
