General Troubleshooting Tips

Modem is not detected on power-up:

lCheck your system BIOS IRQ assignments and make sure that at least two interrupts (especially any unused interrupts) have been assigned to the PCI bus. Go to your system BIOS’s Setup routine and find the 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 interrupts 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.

lTurn off the power and unplug the power cord from the system. Check that the 56K PCI Internal Modem is properly inserted into the PCI slot. Remove the card and reinsert it if necessary.

lTry inserting the PCI Modem into another PCI slot. The slot you are using may have a problem. Try all available slots if necessary.

No dial tone error:

lYou may have too many devices connected to the phone line. Remove all other equipment.

lYour modem may not recognize the dial tone. Use the AT%T19,0,nn com- mand or the Region Selection Program to reconfigure the modem’s Country Setting.

Communications software does not work:

lSome communication software packages need to be configured to the same COM Port and/ or IRQ as the modem.

Nothing appears on the screen when I type In terminal mode:

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