How to dial-up the internet for notebook computers

A: At present, there are three main ways for mobile phones and laptops to access the Internet: infrared access, special RS-232C serial cable access and PC card access. Using these methods to surf the Internet is to use the modem built in the mobile phone or the modem in the PC card to connect the mobile phone with the notebook computer through data transmission lines and infrared rays to realize dial-up Internet access and mobile office. It should be pointed out that in any case, you must first apply to the local mobile communication bureau to open the data service function of the mobile phone SIM card. At present, this service only supports the transmission rate of 9600bps, and the internet access cost is high, so this method is only suitable for occasional use under special circumstances.

There are two ways to access the Internet by using the modem that comes with the mobile phone: infrared access and special RS-232C serial cable access, which is related to the model of the mobile phone.

1, connected through the infrared port of the mobile phone.

First, you need to install the infrared ray of the computer. You need to remind everyone that remember to enable your IR port before installation, which may be disabled in the notebook settings. The infrared indication will appear in the taskbar of WIN95/98.

When the mobile phone starts infrared data association, infrared indicates that the state is active. Double-clicking the infrared indicator with the mouse will pop up the infrared monitor window. In general, the infrared port is set to COM4.

Taking Siemens S2588 as an example, this paper introduces how to access the Internet through the infrared port of mobile phone.

Siemens S2588 provides a built-in modem function, which can be used to connect to the Internet or send/receive faxes without special software. First, activate the infrared ray on the mobile phone: the process is menu-> Other Settings-> Fax/Data -> IrDA. Specific steps for surfing the Internet:

A, install the modem.

In Windows 95/ Windows 98, select Star → Settings → Control Panel → Modem → Add.

B, select "Don't detect my modem", and select from the list (Don't detect my modem; I choose from the list), select "standard modem" and "standard 9600bps modem", and select the port of the modem as "virtual infrared COM port".

C in the "ModemsProperties" window, select the newly installed "standard 9600 baud rate modem" and select "connection →" advanced ". Then select Use Flow Control and Hardware (RTS/CTS), and then select OK → OK → Close.

D. Next, create a new dial-up network. The process is exactly the same as ordinary internet access. Just select the modem you just set up. Then start the dial-up connection just established, and the phone displays "Dialing ...". After connecting, log on to the Internet, but the speed is also 9600bps. It is acceptable to receive emails and browse text web pages.

2. Access through RS-232C serial cable.

Transmission line access and infrared access are basically the same, mainly using the built-in MODEM function of the mobile phone, accessing the Internet through the RS-232C serial cable provided by the mobile phone and the software modem installed on the laptop. Such as Nokia 6 1XX mobile phone, after NDS2.0 is installed, dial-up connection is established, and the modem device is Nokia GSM Data 2.0. Then start the dial-up connection and dial-up the Internet. The advantage is that the position of the mobile phone can be moved, and it is suitable for use in mobile environments such as automobiles, and the line is disconnected.

3. surf the internet with PC card.

If the mobile phone has no infrared port and built-in modem, we can use PCMCIA card as a special wireless modem, insert it into the slot of portable PC card, and install the driver provided by the card. Then we can connect the wireless modem with the matching mobile phone through wires for data transmission and fax.

PC card access is to use PCMCIA card as a special modem, insert it into the PC card slot of notebook computer and install the driver provided by the card, and then connect the PC card with the matching mobile phone through data connection for data transmission and fax. Motorola, Ericsson and other mobile phones generally need the corresponding PC card support.

The installation process of PC card is as follows: first, turn off the power supply of all devices, insert the data fax card into the PCMCIA slot of the notebook computer, then connect the mobile phone and the data fax card with the data cable, and then turn on the power supply, and the device will be automatically detected when the system starts. When the system detects a new data fax card, it will automatically load the driver of the card. If the corresponding software is not found, you will be asked to install the driver manually. After installing the driver, you need to set the modem as a data fax card in WINDOWS95, which can be set to 9600 bit/s at the highest, and other parameter settings are the same as those of the fixed telephone.

In addition, there is a special PC card, which is Nokia's new card-type mobile phone. As the name implies, the card phone is a PC card phone. One end of it is inserted into the PC slot of the notebook, and the other end is left about two centimeters outside, and the part left outside is convex.

After the installation, start the card phone monitoring, you can send and receive short messages, manage the phone number in the card, set up call forwarding, record the called number, modify PIN (personal identification number), security code (security code), prohibition code (call prohibition code) and so on. It basically has all the functions of an ordinary mobile phone. In addition, you can make voice calls, which requires the sound card of the computer to support full DEPLEX. Simulate a modem after installation, occupying COM 5 (adjustable). In other cases, it can be used as an ordinary modem, and it is no problem to send and receive emails, BBS, WWW, faxes, etc.

In fact, these methods are similar, but the transmission medium and specific use are different. For example, some mobile phones have built-in modems (such as S2588), which can directly access the Internet by using infrared rays or transmission lines. Some mobile phones need to use software-simulated modems (such as Nokia Celluar Data Suite), while using a pc card to access the Internet, the modem is the PC card itself, but it will never change!
