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.

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.
