12.The image of this topic is as follows:(2). Synchronous Serial PortMany synchronous serial port types are supported in routers, such as CiscoJustSupports five different types of synchronous serial ports: EIA/TIA-232 interface,EIA/TIA-449 interface, V.35 interface, X.21 serial cable assembly and EIA-530 interface, the corresponding adapter diagram 13, fig 14, fig 15, fig 16, fig17. However, it should be noted that, because the two ends of the adapter connection generally use different shapes (

Serial Port Introduction Serial Port is called serial interface, also known as serial communication interface, according to the electrical standards and protocols including RS-232, RS-422, RS485, USB and so on. RS-232-C, RS-422 and RS-485 standards only regulate the electrical characteristics of the interface, does not involve connectors, cables or protocols. USB is a new interface standard developed in recent years and is mainly used in the field of high-speed data transmission. RS-232: Also kn

is, one-bit and one-bit transmission. We often say that the serial port refers to the RS-232C interface, which was in 1970 by the American Electronics Industry Association (EIA) the serial communication standard jointly developed by Bell systems, modem manufacturers, and computer terminal manufacturers. Its full name is "Technical Standard for Serial Binary data exchange interfaces between data terminal devices (DTE) and data communication devices (

The rules for sending and receiving short messages mainly include GSM 03.38, GSM 03.40, and GSM 07.05. The first two focuses on the technical implementation of SMS (including the encoding method), the latter sets out the DTE-DCE interface standard of SMS (AT command set ). Messages are sent and received in three minutes: Block, text, and PDU. Currently, block is rarely used. text is a plain text method and

indicates successful connection "connect". ----00: A byte, which is only useful if the last byte is 01 (negotiation Progress) or (Connect). 00 indicates no Error control and no Compression. ----80,70,00,00: A DWORD (four byte) that represents the speed of DCE (between modems and modems). Note that this group of values is arranged in a reversed manner, for example, the 00,00 of this example is high byte, and 80,70 is the lower byte, Therefore this val

edge is generally relatively steep, especially for along the sensitive signal, such as clock signal, need to use broadband oscilloscope. 6. RS-232 Level Interface: For low-speed serial communication interface standard, level is ±12v, used for connection between DTE and DCE. 7. RS422 Level Interface: Suitable for multi-point long-distance high-speed communication, two-terminal balanced transmission mode, st

In the field of information security, the industry is paying more and more attention to the security of server operating systems as attack technologies continue to upgrade and data leakage incidents surge. This article introduces two security operating system solutions starting with the study of the classified protection security operating system, and compares the advantages of the general-purpose security operating system compared with the traditional self-developed security operating system.

changed may have to check out the entire project code. Such a large project, the impact of development efficiency is very large, compile for 10 minutes, start for 5 minutes. The agony of waiting is a waste of time, on the other hand, it interrupts the rhythm of development. In the development process, each modified a little content, it is necessary to compile the project, restart the application to verify. Every developer will have to restart frequently, and the amount of waste is huge. Of cour

to give the template a unique name that identifies its characteristics, for example, I want to add a comment to the C # header file, so the template project is named CSharp_HeadFileNote, and then the code is written, so I will take the recently shared senior class in our senior class group. net coding specification.

says that when using envdte, the "call was rejected by the callee" error may frequently occur. This may occur frequently on slow machines due to timeout, but it will also pop up on Fast Running machines. In the downloaded code, it registers an ole message to avoid this error. If you want to run the code correctly in the book, you have to modify some content according to your vs installation. To obtain the current DTE instance, it is not simple, becau

Function In programming often only remember part of the function name, want to quickly locate, but the C # editor function list has no search function, use regular expression search can solve this problem, now write this process as a macro. How to use: Open the VS macro editor and paste the following code. Specify a shortcut key for this macro (optional) Use the shortcut key or run the macro directly, enter the function name. Use F3 to search for the next function that meets the requirements. S

This experiment is to configure a general router as a frame relay switch to provide a frame relay experimental environment for other experiments in this chapter.1.
