1.Make sure the modem is connected to a working phone line. Replace the modem with a working phone to ensure that the phone line is working.

2.Make sure the phone line is connected to the jack marked “LINE.” Incorrect connection prevents the modem from operating properly. Refer to Section 2.2 for modem connec- tion instructions.

Modem dials but does not connect.

1.Make sure the IRQ setting is identical on both the modem and the software in a non-Pnp system. Modem and software must be configured identically.

2.Make sure the phone line is working properly. Replace the modem with a regular phone and dial the number. If the line sounds noisy, you may have difficulty connecting to the remote device.

Modem makes a connection but no data appears on your screen.

1.The remote system may be waiting to receive your data before it begins. Try pressing the ENTER key a few times.

2.Make sure the correct data format (data bits, stop bits, and parity bits) and flow control (RTS/CTS) method are being used.

3.Make sure the correct terminal emulation mode is being used (see communication software manual).

4.Make sure the modem is not sharing an IRQ or COM port with another device in a non-PnP system.

High pitch tone is heard whenever you answer the phone.

1.Make sure Auto-Answer is turned off. Your modem is factory configured to NOT auto-answer. Issue AT&F to factory reset your modem.

Modem experiences errors while communicating with a remote modem.

1.Make sure the DTE speed is the same as the modem connec- tion speed when in Direct Mode (\N1 command in effect).

2.Make sure the remote system and your modem use the same communication parameters (i.e., baud rate, data bit length, parity, and stop bit).

3.Make sure RTS/CTS hardware flow control is enabled and XON/XOFF software flow control is disabled in the commu- nication software.

4.Make sure the data speed is not faster than your computer's
