Modem and ADSL dial-up Internet modem. The English name is modem ". A modem is a computer hardware that translates computer digital signals into pulse signals that can be transmitted along common telephone lines, these pulse signals can be received by another modem at the other end of the line and translated into computer-understandable languages. This simple process completes the communication between two computer computers. The modem can be divided into four types based on the form and Install
through an infrared interface or Bluetooth interface, connect to the Internet through related software. This explains the reason why wireless Internet access cannot be achieved in both laptops and mobile phones. This is entirely because there is no related software support. 2. Connect the mobile phone to the serial port of the laptop through the data cable and use the GPRS mobile phone as the wireless Modem function to access the Internet; 3. Use the GSM/GPRS wireless network adapter through
Linux Kernel compilation details-general Linux technology-Linux programming and kernel information. The following is a detailed description. Unbind the source code package under the/usr/src/directory to obtain the source code directory/usr/src/linux-2. ***/. before doing anything to the kernel, we recommend that you take a look at its README file and Documentation/Changes file, from which you will get a lot of useful information. This information will help you avoid unnecessary troubles in the s

Linux CDMA dialing (reprinted)-Linux general technology-Linux technology and application information, the following is a detailed description. It is quite painful to be unable to access the Internet, but I don't always stay in the same place. Although CDMA wireless Internet access is slower, it's so good to be able to access the Internet! After deciding on the Internet solution, another problem emerged.
Currently, Linux usually comes with a rich array of hardware drivers, which is not an order
USB or PCMCIA wireless card is plugged in correctly, and in order to see if the wireless card is properly connected to the system, enter:Parameter explanation:-a displays the status of all network interfaces for the host. Unlike the simple ifconfig command, all adapters connected to the current system network interface can be seen after the-a parameter is added.As shown in 4, we can see that there is a wireless network card named Wlan0 compared to 3,
Similar to ipvsxp, the Linux operating system of Ubuntu has a batch of system services started at random. Windows XP users with a slightly understanding of computers will disable unnecessary services to increase the boot speed; now we have installed the Ubuntu operating system. we also need to know about the Ubuntu service ,... similar to IPVs XP, the Linux operating system of Ubuntu has a batch of system services started at random.

same time, it can be said that two birds in one fell swoop. The machine's external engineering plastic spray silver Matt paint, the internal is black, slightly sand texture, I think the appearance of t2000d5b is not t2000d5 full black so sedated. The appearance of the machine can only be regarded as normal. The joints of the mold are relatively fine, but there is a large gap between the four USB ports, and it is easy to become a place where dust is accumulated.

, you need to enter the emergency repair mode, which may solve the problem and at least copy important files.
---- The method for entering the emergency recovery mode is not complicated. Enter the following parameters at the boot prompt:---- Boot: linux rescue
---- You can get the Boot prompt using the following method.
It is released with the disk in Linux or by boot. the imgfile is written to install the boot floppy disk boot system. Usually this requires urgent disk repair, CD installation,
after major system changes that affect the files required for your system startup. 10. Install sysv-RC-conf and disable services that you do not need to start. For example, my computer does not have Bluetooth or PCMCIA, so I do not need to start it. Therefore, it is prohibited to drop services that you do not have and do not need. Code: sudo apt-Get install sysv-RC-conf and then: Code: sudo sysv-RC-conf is a reference for some service options. For mo
installed and detached by users at any time. The drivers of these peripheral devices are also called flow drivers, which can be dynamically loaded by the Device Manager at system startup or at any time after startup. These drivers usually exist in the form of DLL dynamic link libraries, and the loaded drivers can only run as user roles. In wince, typical load-able drivers include PCMCIA Driver (PCMCIA. DLL
That is, the prefix of the Cross-compiler name is arm-Linux-If you use the toolchainIf the name is different, you need to modify it accordingly. For example, the author uses arm-iwmmxt-Linux-gnueabi-gccTherefore, you must change it to cross_compile = arm-iwmmxt-Linux-gnueabi-.

The line starting with "mapping" is used to determine the logical interface name for the physical device interface to be started. The first line of the "mapping" field starts with "mapping", followed by the pattern matching (such as eth *) with the same glob command syntax in shell *). Each "mapping" field must contain a script definition, which uses the physical device interface name as the parameter, all the following fields starting with "map" (e

For example, the ora command I installed does not exist. Method 2: display the/proc/dev file, which records some hardware information of the system, for example: cat/proc/dev method 3: to find a specific usb device, you can use the lsusb command to list all usb devices.
