Section Five - Troubleshooting

Your modem is designed to provide reliable and trouble-free func-

tionality. However, should you experience any difficulty, the information

contained in this section will assist you in determining and resolving the

source of the problem. If you can not resolve your situation after reading

this chapter, contact your dealer or vendor for assistance.

5.1 Modem does not respond to commands.

1. Make sure the modem is not configured with a conflicting COM port and IRQ

setting (see Section 2.2.1). Your modem can not be configured as COM4

(recommended) if another device in your system is also configured as COM4.

Similarly, IRQ settings may not overlap.

2. Make sure the communication software is configured with the correct COM

and IRQ settings (same COM port and IRQ as the modem). Your com-

munication software will not be able to send or receive any data if it is not

configured to match the COM and IRQ settings for the modem.

3. Make sure the modem is properly initialized by the communication software.

Your modem may have been improperly initialized by the software because

you have selected an incorrect modem type. You may also be prompted to

enter an initialization string” by the software. Use AT&F as your initialization

string.

4. If you are running Microsoft Windows 3.1, make sure that the modem is

properly configured in Windows (see Section 3)

5.2 Modem dials but does not connect.

1. Make sure the IRQ setting is identical on both the modem AND the software.

2. Make sure the phone line is working properly. A noisy line will prevent proper

modem operation.

5.3 Modem makes a connection but no data appears on your

screen.

1. Make sure all communication parameters (baud rate, data, stop, and parity

bits) are properly configured and are identical on both sides. Be certain

hardware flow control (RTS/CTS - default) is enabled in both the modem and

the communication software.

2. Press the ENTER key several times. The remote system may be waiting to

receive your data before it begins.
