Communications Software Does Not Work

Some communications software packages need to be configured to the same COM Port and or IRQ as the modem. See “Installing the Modem” for information on how to determine your COM Port and IRQ number.

The communications software you are using may not support this modem. See “In- stalling and Configuring Communications Software” section of this manual.

If you are trying to use different software that supplied with the modem (some mod- els of this modem may be shipped without communications software), try installing the supplied software and verify its functionality with the modem.

Nothing Appears On The Screen When I Type in HyperTerminal

Issue the AT command ATE1 (see Appendix B: AT Commands) to the modem to enable command echo. This will let you see what you type.

Can’t Connect at 56K

Note: Current FCC regulations limit your maximum connection rate to 53K bits/s.

The number you are calling may not support V.90 or K56flex protocols. Some ISPs (Internet Service Providers) have special numbers that you must call to connect to 56K. Contact your service provider and ask if the number you are calling supports V.90 or K56flex connections.

Check the maximum speed setting in the Modem Properties window. In Control Panel, double-click the Modems icon. Highlight your modem by clicking once on the icon next to your modem in the list, then click Properties. Select the General tab and look at the setting in the Maximum speed box. Make sure this is set to 115200.

You may have other telephone devices connected to the phone line. To help your modem achieve the best connection possible, remove all extra devices connected to the telephone line when the modem is in use. This includes extension phones, an- swering machines, cordless phone bases, caller ID boxes, and their cables.

Keep the length of your phone line cable to 10 feet or less. Don’t lay your phone cords close to an electrical appliance like a refrigerator or air conditioner unit. High current devices can transmit a 60 cycle “hum” to your modem through the phone cord. This may cause frequent renegotiations or line disconnects.

The telephone line conditions at the time of your call may not let you connect at 56K. The modem has a connection sequence of K56flex, then V.90, then V.34, and
