DCD (Data Carrier Detect-carrier detection) DTR (data Terminal ready, terminal prepared) DSR (data Set Ready), RTS (Request to send) CT S (Clear to send clean send) in these five control signals, DTR and RTS are DTE devic

DCE and DTE. Electrical characteristics Specify the encoding that DTE and DCE must use, must use the same voltage to describe the same state, and must be using the same width of the signal bits, which determine the data transfer rate and distance that can be reached. Features specify the functions to be completed for each switching circuit. Depending on the functional nature of the interface, the procedure

In 2000, researchers at William Mary College in the United States, Serge, and others at the Usenix 4th annual Linux Showcase conference Conference, published the title "Domainand Type Enforcement for Linux "article. The first time this article used the DTE model for Linux, the DTE Linux prototype system was implemented.The same year, the NSA's Stephen Smalley and others released the open source Linux securi

is a public header, and a hole-shaped joint is a mother. The appearance of the 9-pin serial port is shown in 2. Figure 2 DB-9 exterior Diagram From figure 2, we can see that in the 9-pin serial port connector, the pin definitions of the public and mother heads are different, which requires special attention. So what are the functions of these pins? The functions of the 9-pin

off. The speed of serial data is usually expressed in bytes bits-per-second (bps) or baud rate (baud) transmitted per second. This value represents the number of 0 and 1 sent out per second. A long time ago, 300bps was fast, and now the computer can handle up to 430,800 RS-232 rate. The unit that represents the baud rate also has KPBS and mbps,1kps=1000bps and 1mbps=1000kbps. When a serial device is common

In software encryption protection technology, a common protection method is license authorization based on hardware fingerprint. This article will introduce the specific hardware fingerprint acquisition technology in detail and provide a demo source code program. Hardware fingerprint encryption means that after a user obtains and installs the software for free, the software obtains some hardware information (such as the hard disk serial number and BO

In the first article, I believe that many people can do this without reading it. However, anyone who has used the Microsoft SerialPort class has encountered this embarrassment. When the serial port is closed, the software will be deadlocked. Oh, my God, I am not so arrogant. Forget it. Don't be so absolute. 99.9% of people have encountered this problem. I think only half of them actually solve the problem. The other half closed their eyes and hoped th

Recently, due to the needs of the project, the need to get the machine's hard drive serial number and MAC address information, under C #, it is easy to obtain this information, but in the C + + program feel more trouble.

On the internet to find a few examples of traversing the serial port, either the code is not complete, or there is a bug, such as reading the serial number is more than 10.After my finishing, now share the final code, VS2008 under the compilation.This method is also useful for traversing Windows power-on startup items with just a few modifications.void Cenumportdlg::enumport (void) {HKEY HKEY; LPCTSTR lpsub

The RS232 interface is a standard for serial communication jointly developed by the American Association of Electronic Industry (EIA) and bell system, modulation regulator manufacturers and computer terminal manufacturers in 1970.
