Mycom is a serial communication class and has complete code in the previous article of this blog. (C # Serial Communication Programming (modified ))The following is the source code of the serial communication test program. The mycom class is stored in this project.You can implement simple serial communication, and hope

Android communication protocol and Android communication protocol I. TCP/IP protocol (Transport Layer Protocol) 1. Socket and ServerSocket Socket is the intermediate abstraction layer for communications between the application layer and the TCP/IP protocol cluster. Socket is a group of interfaces. In the design mode, Socket is designed as the facade mode, it hides the content of the complex TCP/IP protocol

Summary of Serial Communication Knowledge in mobile development and summary of Serial Communication Knowledge Summary of mobile development Serial Communication Knowledge the original APP only displays append in the text box when it receives serial data. There are no other functions. Very helpless, many things need to be explored by themselves, for example, the

End-to-end asynchronous communication protocol:Features and formats:The characteristic of a start-stop asynchronous protocol is a character transfer, and the transmission of a character always begins with the starting bit, ending with a stopped bit, and there is no fixed time interval between the characters. Its format is shown in 3. Each character is preceded by a starting bit (low level, logical value 0), the character itself has a 5~7 bit data bits

Android-based HTTP Communication and Android-based HTTP Communication I recently learned about HTTP Communication in MOOC Android and summarized it myself. I have read many blog posts and thank you for sharing them. The content of this article includes:1. HTTP Overview2. Differences between HTTP/1.0 and HTTP/1.13. HTTP request header, response header, and status

This article takes the Visual C + + data collection and the serial communication to measure the application actual combat as the reference tutorialThis article is suitable for VC + + Serial Communication IntroductionFirst, page layout and add control1, install the vs2010.2, create a new MFC project based on VC + + CommNote: Click OK, then next, to change the application type to dialog base. Next to the last

The network port uses the 1000M rate time to appear the network communication loses the packet +idc the computer room managed server communication is not smooth. Network failure: Switch port 1000M, network card is 1000M, NIC configuration is normal. You lose the packet at the interval of ping. The performance is packet loss in network communication, and other

Http://www.cnblogs.com/csdev/p/4696686.htmlIn the previous communication between C # Server and Java client based on Networkcomms V3 communication Framework, the passing of characters in C # side and Java side communication was discussed, and a friend mentioned that if an integer of type int was passed, the encoding problem would occur.Found an article on the int

;Second handshake: The server receives the SYN packet, it must confirm the customer's SYN (ACK=J+1), and also send itself a SYN packet (syn=k), that is, the Syn+ack packet, when the server enters the SYN_RECV state;Third handshake: The client receives the server's Syn+ack packet, sends the acknowledgment packet ack (ACK=K+1) to the server, the packet is sent, the client and the server enter the established state, and the handshake is completed three times.The so-called three-time handshake is a

Due to the improper arrangement of the study plan, the perception of WCF has been stagnant. Recently, I used WCF again in my work. I can see the blog post about duplex communication from instructor Jiang and try it out, accumulate. The original thought of WCF duplex communication is that the original client can call the method of the server, and the server can also call the method of the client. After readi

There are several main ways to communicate threads in a Linux system:* Lock mechanism: Includes mutex, condition variable, read-write lockProcess communication: Pipe: A pipe is a half-duplex mode of communication in which data can flow only one way, and can only be used between processes that have affinity (parent-child processes). In addition, the pipeline transmits an unformatted byte stream, and

Commonly used inter-process communication includes pipelines, message queues, and shared memory. MPs queue The first pipeline was used to share data between kinship-related processes. The parent process first creates an MPS queue, and then fork () generates a sub-process. The sub-process automatically shares the access permission to the MPs queue. This pipeline has no name (only one identifier in the process is identified), so it is also called an an

Inter-process communication (9), inter-process communication 1. Preface all examples in this article, based on RHEL6.5 platform (linux kernal: 2.6.32-431. el6.i686 ). 2. the introduction of shared memory is also an IPC, which is currently the fastest IPC. It is used to map the same memory zone to the address space of different processes sharing it, in this way, the comm
