An experienced modem user can configure the program’s software to change the way the software interacts with a modem and configure the modem to change the way it operates.
Configuring Your Communications Software
For Windows 95/98/2000 and Windows NT:Communication programs designed for these operating systems normally do not need to be manually configured, since they use the Plug and Play configuration of the Windows modem driver.
For DOS and Other Operating Systems:Communication programs designed for DOS and other operating systems, however, may need to be manually configured to work with your modem. Though each communications program is different, the following procedure should work with most of them.
1.Turn on your computer and run your communications program.
2.Find the dialog box or menu that lets you select your modem. (In Windows Terminal select Settings Modem Commands; in HyperTerminal select File Properties Phone Number; and in the communications program select Configure General Configuration Communication Change Modem.
3.Choose your modem from the program’s modem list. If it isn’t listed, choose a generic modem and modify the settings as necessary.
4.Change the modem initialization string, if necessary. The factory default configuration works well for most purposes. To load the factory default configuration, use AT&F. To load a custom configuration that was saved using the &W command, use ATZ. Note that the Z command must be in a command string by itself. For a Macintosh, the initialization string should include the &D0 command. If you do not want the modem to always answer the phone, add S0=0 to the string. To use Caller ID with the modem, add S0=2 to the string (Caller ID information is sent between the first and second rings, so the phone must ring at least twice before the modem picks up the line). Depending on the software, you might have to end the string with a carriage return character (^M).
Note: To change the modem’s default configuration, type new commands in the communication program’s terminal window, adding the &W command to store them in the modem’s nonvolatile memory. For instance, to create a default configuration for a Macintosh computer that turns off autoanswer, type AT&F&D0S0=0&W. The new configuration loads automatically whenever the modem is turned on or receives the ATZ command.
