Can i increase acesses & DOWNLOAD SPEED if i use high speed external modem.?

Question

I am using dial up connection using 56 kbps internal modem. can i increase acesses & DOWNLOAD SPEED if i use high speed external modem.
I don't want to change to cable or broadband service
as dial up which i am using is free to me.

Answer 1

No because the phone lines have limited bandwidth. You can get software to help but you will not get speeds as good as DSL or Cable.

Answer 2

First make sure the modem will work, it may only be used for high speed DSL or T1 lines. It may help a little, but the connection speed is what needs to be upgraded, changing the modem may possibly help a little, but you will not see a considerable change.

Answer 3

No.

You can get a single-channel ISDN modem that will get up to 64kbs on a phone line (but you would have to pay for it) and it would still be slower than f**k.

Unless you want to shell out some cash, you are stuck at 56k.

Answer 4

Your receive % is constrained by ability of the SLOWEST leg of your connection - which works to be out on the information superhighway someplace. receive from a server that you've a speedier connection to. maximum information are available on more beneficial than one server.

Answer 5

Through some parameters you can optimise the Internet speed through your internal 56kps modem.

If you live in an area of the country where neither DSL nor cable modems are available, you're still relying on your trusty 56K modem to connect to the Net. While 56K modems are a lot faster than their 33.6K predecessors, they really don't allow you to connect at 56K. That's because FCC regulations limit the 56K modems to a maximum connection speed of 53 Kbps. And if your connection goes through more than one analog switch, which is very likely, your 56K modem will only get a connection speed of somewhere between 45 Kbps and 50 Kbps.

However, the connection speed between your modem and your ISP only represents one half of the picture. The other half represents the connection speed between your modem and your computer. In this article, I'll show you how to tweak a few settings that will optimize that connection. As I do, I'll pass along some additional Wizardly tips that will help you get the most out of your connection to the Net.




Understanding The COM Port


As you may know, Windows uses the COM port to transfer data back and forth between your computer and your modem. This means that regardless of how fast your modem connects to the outside world, it must transfer information to your computer though the COM port.

If you have an internal modem, the board contains its own COM port that it adds to your computer. Chances are good that an internal modem's COM port is already set to optimal values.

If you have an external modem, the modem is connected via a cable to the COM port built into your computer, which is also known as the serial port. You'll discover that these Windows default settings are less than optimal.

Wizard Note: There are two types of 56K modems on the market today—WinModems and conventional modems. WinModems do not have built-in controllers and just provide the connection and translation to the phone line—your computer's CPU does the real work. The main advantage of leaving out the controller is that it makes WinModems extremely cheap—you can get your hands on a WinModem for $50 or less. The main disadvantage of this scheme is that your modem's performance will suffer when the CPU is busy processing a big operation.





Tweaking The COM Port


You can tweak the COM port settings from within Device Manager, which you can access by right clicking on My Computer and selecting the appropriate tab. Then, scroll through the list and double-click the Ports branch. Now, double-click the communications port to which your external modem is attached. At this point, select the Port Settings tab to access its settings, as shown in Figure A.

Figure A: On the Port Settings tab, you'll find some of the settings you can adjust for the COM port.











As you can see, the default value for the Bits Per Second setting is 9600, which controls the rate at which data can flow through the port. As you can imagine a setting of 9600 is fairly slow and represents a big bottleneck. To crank up the rate at which data can flow through the port, choose a value of 115200. Keep in mind that while you can select higher values than 115200, doing so won't offer any additional benefit, as the highest speed that the chip running the COM port can handle is 115K.

You should leave the default values for the Data Bits, Parity, and Stop bits settings as they are. These values represent standard settings and will work fine for all your communications needs.

Investigating Flow Control


Towards the bottom of the Port Settings tab is the Flow Control setting. This setting has three values that you can use to determine how data flows from the modem to the COM port. In this type of communication system, the modem keeps sending data to the COM port until the COM port is full and tells the modem to stop. The COM port then processes the data and passes it on to the CPU. At this point, the COM port lets the modem know that it's ready to accept more data and the process starts all over again.

The flow control system is designed to prevent a problem known as data overrun, in which the receiving device is overrun with data faster than it can process it. The default setting Xon/Xoff is a software method of flow control. In this method, two special characters (Xon and Xoff) are used to control the flow of data between the modem and the COM port. The Xoff character, which stands for transmit off, is used to tell the modem to stop transmitting. When the COM port is ready to receive data again, it sends the Xon character, which stands for transmit on.

The next setting is Hardware, which uses a wire in the cable to signal when to start and stop sending data. As you can imagine, hardware flow control is much faster than the Xon/Xoff method because it doesn't have the overhead necessary to manage the software commands.

Keep in mind that not all modems support hardware flow control. Check your modem's manual to find out what type of flow control is recommended. If you do use hardware flow control, make sure you have a good quality modem cable.

Wizard Tip: To boost the performance of your overall telecommunications sessions, you can configure your modem to dial faster. To do so, you will need to add a special command to the modem's initialization string. This command is the ATS11=50 command and sets the length of each touch-tone pulse to 50 milliseconds-the fastest most phone systems can handle.

To do so, open Control Panel, double-click on the Modems icon, select your modem, click on the Properties button. Then, select the Connection tab, click on the Advanced button, and type S11=50 in the Extra Settings text box.

Two things to keep in mind: First, you don't have to type the AT part of the command as it already exists in the modem's initialization string. Second, if you already have commands in the Extra Settings text box, simply separate the new command from the existing commands with a space.

The next part of the COM port system that you'll want to investigate are the FIFO buffer settings, which are designed to take advantage of the FIFO buffering system built into COM port's UART chip. The UART chip is the brain behind the COM port.

The FIFO buffering system is designed to work with and enhance the basic operations of the flow control system. Basically, the FIFO system allows the UART chip to continue to receive data and store it in a buffer while the CPU is busy. Since data is going both ways through the UART, the FIFO system actually has two buffers. The Receive Buffer stores data coming in from the COM Port and the Transmit Buffer stores data heading out to the COM port.

To investigate the FIFO settings, click the Advanced button at the bottom of the on the Port Settings tab. You'll then see the Advanced Port Settings dialog box.

Normally the default settings are fine. However, you may want to experiment with adjusting the settings if you believe that your system is experiencing data overruns. Examples of such situations are excessive errors during file transfers, poor overall performance, or jerky multitasking during file transfers

Guidelines For Adjusting The Receive And Transmit Buffers


When you do adjust the Receive Buffer and Transmit Buffer settings, you should keep the following guidelines in mind:

The Receive Buffer slider allows you to set the size of the buffer to values of 1, 4, 8, and 14 bytes. The default is 8 bytes, which should be sufficient for most situations. When you increase the value to 14 bytes, of course the buffer can hold more data. However, this can cause an overrun situation and data could get lost. When you decrease the setting, the receive buffer holds less data and will fill up faster. This causes the UART to communicate with the CPU more often, which, in turn, slows down the UART's ability to accept incoming data.

The Transmit Buffer slider allows you to set the size of the buffer to values of 1, 6, 11, and 16 bytes. The default is 16 bytes, which should be optimal for most systems. However, if you're experiencing problems uploading files, decrease the size of the buffer. When you do, the UART communicates with the CPU more often, which slows down the rate at which data is sent to the transmit buffer. On the other hand, when the buffer is set to the default, the UART communicates with the CPU less and the system's performance improves during uploads.

Answer 6

No.

You cannot "surf" faster then what the connection supports, no matter what equipment you use.
