Plug-N-Play settings. These settings can be found within the “Advanced,” “PNP/ PCI Configuration,” or “Plug-and-Play Configuration” sections depending on the BIOS Manufacturer. Next, verify that at least two IRQs have been set so that the PCI bus has access to them (some BIOS don’t allow individual selection of interrupts to ISA, Plug-N-Play, or PCI). These settings can be called ICU, ICU/PCI, PCI, or PNP depending on your BIOS version and manufacturer. Do not set all the inter- rupts to “ISA” only or to “Legacy ISA”. Pay attention to the IRQ usage of the other peripherals in your system. Do not reassign an interrupt that is already in use by an ISA card to the PCI bus.

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.

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 ATX0 to have the modem ignore (not look for) the dialtone before dialing. (See Appendix A for information on how to use AT commands.)

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 the “Installing the Modem” for information on how you determine your COM Port and IRQ number.

Does the communications software support this modem? See the Installing and Con- figuring Communications Software section.

If you are using a different software from the one supplied with the modem (some models of this modem may be shipped without communications software), try in- stalling the supplied software and verify its functionality with the modem.

Nothing Appears On The Screen When I Type

Issue the AT command ATE1 to the modem to enable command echo. This will let you see what you type.
