Common Problems
No Dialtone Error
Make sure you have connected the phone cable into the right connector on the back
of the modem. See “Figure 7: Connecting Devices.”
You may have too many devices connected to the phone line. Remove all other equip-
ment.
Your modem may not recognize overseas dialtone. Use the AT command string “ATX0”
to have the modem ignore the dialtone before dialing.
Communications Software Does Not Work
The communications software must be configured to the same COM Port and IRQ
as the modem.
Does the communications software support this modem? See “Installing and Config-
uring Communications Software.”
If you are using different communications software from that supplied with the mo-
dem, try installing the supplied software first to verify its functionality.
Nothing Appears On The Screen When I Type
Issue the command ATE1 to the modem to enable command echo. This will let you
see what you type.
Cannot Connect at 56K
Note: Current FCC regulations limit your maximum connection rate to 53Kbits/s.
The number you are calling may not support V.90 or K56flex protocols. Some Inter-
net Service Providers have special numbers that you must call to make 56K connec-
tions. Contact your service provider and ask if the number you are using supports
V.90 or K56flex.
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 the modem and then click the Properties button. 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 achieve the
best connection possible, remove all extra devices connected to the telephone line
