Multiport Serial debugging, you can connect with a machine, can also use RS

基于ARM9和μC／OS-Ⅱ的Modbus通信协议的实现-Based on ARM9 and μC/OS- Ⅱ of the Modbus communication protocol to achieve

多串口调试，可以在同一个机子上连接，也可以用RS-232连接到两个机子上测试串口通讯，-Multiport Serial debugging, you can connect with a machine, can also use RS-232 connected to the two machine test serial communications,

C语言开发串行通讯程序库，可用来进行串口开发用-C-language development serial communication libraries, which can be used for development with Serial

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

RCC底层通信程序 包含协议和测试报告-RCC SerialPort

Delphi串口通信控件-支持4个端口-Delphi serial communication control-support four ports

NRF模块的接收程序，基于最基本的51单片机，很有用哦-NRF module to receive the procedure, based on the most basic single-chip microcomputer 51, is useful Oh

串口通讯编程包括网络流量监控的等程序VC++编程语言与大家共享-serial communications programming, including network traffic monitoring procedures VC programming language and share

vb演示Mscomm各种通信功能-vb demonstration of various communications functions Mscomm

利用新型单片机c8051f020进行的编程，该单片片机具有很高的性价比。-new SCM C8051f020 use the program, the single pieces of the machine has a price.
