10.6 Advanced Modem Settings

Because so many people consider the Internet such an important PC feature, Windows XP lets you fine-tune its dialing, modem, and Internet settings to within an inch of their lives. You should consider the rest of this chapter optionalor power-userreading.

To adjust the settings for your modem's dialing patterns, choose
StartControl Panel. In Classic view (see Section 8.5, page 243), double-click Phone and Modem Options. (See Chapter 9 for more on the Control Panel window.) The resulting dialog box (Figure 10-8, left) consists of three major tabs, each serving important functions.

Figure 10-8. Left: This dialog box has two priorities: to establish rules for dialing out, and to define as many different sets of rules for dialing as you need. If you're setting up dialing properties for a desktop computer, you won't need to change these settings after the first successful call. Right: Setting up a new dialing rule.

10.6.1 Dialing Rules Tab

The Dialing Rules tab (Figure 10-8, left) is made for travelers. As you move from place to place, you may wind up in locations that have very different dialing requirements. The area code may change, not to mention the requirement to dial 9 for an outside line, the availability of touch-tone dialing, and so on.

To set up the dialing rules for your current location, click its name and then click the Edit button. The New Location box appears (Figure 10-8, right), bristling with enough controls to make your modem sing, dance, and stand on its head.

10.6.1.1 General tab

Here are the guidelines for filling out this dialog box:

Location name, Country, Area code. These boxes inform Windows where you're presently located. When your modem dials another city or country, Windows XP will know when to dial a 1 (and a country or area code, when necessary) before dialing.

To access an outside line for local/long distance calls. In many offices and hotels, you must dial a number (usually 8 or 9) to get an outside line. If you enter numbers into these text boxes, Windows will dial them before the regularly scheduled Internet number.

Use this carrier code to make long distance/international calls. These options specify the codes that you have to dial, even before the area code, when dialing internationally. For example, in the United States, the long distance carrier code is 1. For international calls, the carrier code consists of the digits you dial before the country codeto make international calls from the United States, for example, the carrier code is 011.

To disable call-waiting. If you have call-waiting service, that little beep that announces another incoming call can scramble your Internet connection. Fortunately, Windows XP will be delighted to automatically disable call-waiting whenever you use the modem. Turn on this checkbox; from the drop-down list to its right, choose from the list of the common call-waiting disabling key sequences (*70, 70#, and 1170). (If you don't know which sequence works for your local phone company, check the front of your phone book.)

When the modem disconnects from the Internet after your online session, call-waiting automatically returns to the phone line.

Tone or pulse dialing. Specify whether your telephone service is touch-tone (push-button) or pulse (as on old-fashioned rotary-dial phones).

10.6.1.2 Area Code Rules tab

It used to be easy to dial the telephone in America. For local calls, you dialed a seven-digit number. Calls to other area codes started with 1 and then the area code.

Not any more. Many metropolitan areas now utilize ten-digit dialingan insidious system that requires you to dial the full area code even for your next-door neighbor. Worse, some cities have several different area codesnot all of which require a 1+ area code dialing pattern. To confuse things further, in some cases, you dial only the area code plus the seven-digit number.

To clue your modem in on the vagaries of your own area's area code practices, click the Area Code Rules tab. From there, set up the dialing sequences for certain locations by clicking the New button to open the New Area Code Rule dialog box. The resulting options (Figure 10-9) let you specify the area code and three-digit prefixes. Click OK to return to the New Location dialog box.

Figure 10-9. This dialog box can handle any weird and convoluted area code rule in your town. (If there aren't special rules yet in your area, it's only a matter of time.) When your local phone company changes the rules, don't forget to open this dialog box and explain the changes to your modem.

10.6.1.3 Calling Card tab

If you, the shrewd traveler, feel that there's a better use for your money than paying most of it to your hotel's $3-per-minute long distance scheme, this dialog box is for you. It lets you train your modem to bill its calls to a calling card (Figure 10-10).

Figure 10-10. Windows XP already knows about the dialing requirements for most major calling cards. When you choose one from the Card Types list box at top, Windows XP automatically fills in the fields at the bottom with the correct information. On the remote chance you can't find your own card, just type in the necessary dialing codes manually.

Figure 10-3). When the dialog box shown at left in Figure 10-3 appears, use the "Dialing from" drop-down list to choose the name of the dialing-rule setup that contains your calling card configuration. Now click Dial to start your call.

10.6.2 Modems Tab

All the preceding discussion concerns only the first of the three tabs in the Phone and Modem Options program. The second tab, called Modems, is simply a list of the modems currently connected to your PC. (Most people not in Oprah's tax bracket, of course, see only one modem listed here.)

Double-clicking the name of your modem opens its Properties dialog box, which bursts with technical parameters for your modem. In general, you'll need to visit these dialog boxes only when troubleshooting, following the instructions of some telecommunications geek from your modem company. Two of them, however, are more generally useful:

Change the speaker volume. The modern modem may have revolutionized computer communications, but the squealing sounds it makes could wake the deador, worse, the spouse. To turn the speaker off, so that you no longer hear the shrieks every time you dial, click the Modem tab (Figure 10-11), and then drag the Speaker volume slider to Off.

Figure 10-11. The Modem tab of the Modem Properties dialog box. Many people, perhaps thinking wishfully, set a speed higher than the modem's rated speed. Unfortunately, the speed doesn't actually improve as a result.

NOTE

The slider affects the speaker volume only while it's dialing and making a connection to another computer. After the connection is established, the speaker always goes silent, so you don't have to listen to all the squawking noises that indicate data transmission.

Wait for the dial tone before dialing. This checkbox (also on the Modem tab, as shown in Figure 10-11) is normally turned on. If you travel abroad with your laptop, however, you may experience trouble connecting if the foreign country's dial tone doesn't sound the same as it does back home. Turning off this checkbox often solves the problem.

10.6.3 Advanced Tab (of Phone and Modem Options)

These controls, too, are extremely advanced options that you'll never need to adjust except in times of intense troubleshooting.
