Among them, hetian Yu seed material is the object that collectors compete to snatch. In fact, this is a misunderstanding of the knowledge of jade. The truth is that, whether it is mountain materials, litter, mountain flow materials or Gobi materials
This kind of photograph can be a bit of ash, looking at the Gobi is not the kind of desolation, so we through some means, let this picture can better show the Gobi Desert style.

Modem generally has 2 modes of operation, one is the normal mode of using dial-up software, one is the routing mode of automatic dialing. In normal mode, you do not need to set up your modem, use the default. While the routing mode needs to be set up, modem with its own flash memory,

ADSL can provide users with more than 6Mbps of data transmission bandwidth, this condition is enough to achieve Internet access, video on demand and access to the local area network. ADSL can achieve bidirectional transmission rate of 640 Kbps in interactive mode. ADSL technology has increased the bandwidth of the existing public telephone network data transmission 50 times times. The transmission of voice, text, and low-resolution images is no longer limited by bandwidth.
ADSL technology can b

Call data using mobile phones
There are countless types of mobile phones in the current market, but most of the mobile phones with data transmission capabilities use a common communication method to communicate with the data MODEM in mobile phones or network providers. The Linux abstract Control Model (ACM) is designed to
This article includes common classic problems in broadband sharing. You can take a look at any questions about network sharing!
1. What are the benefits of shared bandwidth?
Now, broadband networks have been activated in many places, and the network speed is greatly improved compared to that of the ordinary MODEM in the past, while the network bandwidth required for browsing web pages and chatting on the Internet is not high, if you just want a comput
CommEvent attribute contains the latest event or wrong numeric code, you can read the CommEvent attribute value in the program to understand the communication status. The OnComm event is closely related to the CommEvent attribute and used together. When any OnComm event or error occurs, this will change the CommEvent attribute value. In the OnComm event processing process, you can determine the CommEvent attribute value. For different attribute values to be transferred to different event proces
") for file transfer, without starting the server. The method is to use the ipxcopy command on one computer to start the receiver and use the "ipxcopy file name" command on the other computer for transmission. The file name can be a wildcard character, you can also use the/s option to specify files that include subfolders. Of course there are other methods, so I will not introduce them here.
The above is the connection method of LAN. Next we will talk about the Internet method. There are two wa
We know that the use of RS-232C protocols is well-developed in some areas of electrical and mechanical, and the basics of this are also described in previous articles. So as a supplement, we next to the RS-232C protocol interface signal to a comprehensive summary. I hope this will help you.

A security vulnerability was found in the Wired modem of ARRIS SURFboard. Attackers can remotely attack about 1.35 billion of devices around the world.Security expert David Longenecker explained that a security vulnerability exists in a very popular wired modem produced by ARRIS (formerly Motorola), affecting billions of
After the ADSL installation is completed, you will be waiting for the installation personnel to come to the door for installation. You should know about the installation method. Otherwise, you will not know how to solve the problem if you change the installation method in the future or encounter some minor problems.
The installation of ADSL mainly includes: 1. installation of equipment and lines; 2. Installation of software.
First, let's take a look at the installation and cabling of ADSL device
