remain connected until the program terminates. Some programs can disconnect without exiting the program. If this is the case, try issuing the software’s connection command. If more than one communications program is open, they may conflict with each other. Make sure all other communications programs are closed and try to make the connection again.

•If using legacy software, the COM port setting may not match the COM port that Windows assigned. Compare the COM port setting in your software to the COM port reported in Windows. To view your modem COM port settings:

•In Windows 95/98, select Start Settings Control Panel Modems, and then Diagnostics.

•In Windows NT, select Start Settings Control Panel Modems. Click Properties.

•In Windows 2000/XP, click Start Settings Control Panel Modem and Phone Options Properties.

•Another expansion card (such as a sound card) may be using the same COM port, memory address, or interrupt request (IRQ) as your modem. See Chapter 2 for information on verifying the configuration for your operating system. Look for conflicts with other devices installed on your computer. Resources are assigned at power up by the computer’s BIOS. If the resources assigned to the MultiModemZPX conflict with the resources of another device, the resources of the second device have to be changed. Select the port the conflicting device is on and change it to resolve the conflict. If you need to change switches or jumpers on the conflicting device, refer to the device’s documentation.

•If you have another MultiModemZPX, install it and try to make a connection.

The modem dials but cannot make a connection

Several reasons why the MultiModemZPX fails to make a connection include:

•Lack of a physical connection to the telephone line.

•A wrong dial tone.

•A busy signal.

•A wrong number.

•No modem at the other end.

•A faulty modem, computer, or software at the other end.

•Incompatibility between modems.

Narrow the list of possibilities by using extended result codes. If you disabled themodem’s extended result codes, enable them by entering ATV1X4 in a terminal window and press Enter. When you dial again, the modem reports the call’s progress.

•If the modem reports NO DIALTONE, check that the modem’s telephone line cable is connected to the modem’s jack and the telephone wall jack. If the cable looks secure, try replacing it.

If that doesn’t work, the problem may be in your building’s telephone installation. To test the building installation, plug a telephone into your modem’s telephone wall jack and listen for a dial tone. If you hear a dial tone, your modem may be installed behind a company phone system (PBX) with an internal dial tone that sounds different from the normal dial tone. In that case, the modem may not recognize the dial tone and may treat it as an error. Check with your in-house telephone switch (PBX) personnel or the PBX system manual to see if you can

change the internal dial tone. If you can’t, change your modem’s initialization string to include X3, which makes the modem ignore dial tones.
