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) 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 (see Section 2.4).

V.42bis/V.42/MNP2-5 does not work

2.You must enable the hardware flow control (RTS/CTS) option in your communication software.

3.Make sure your DTE speed is set at 38400 or 57600 bps.

4.Use a streaming file transfer protocol such as Zmodem or Y- Modem-G.

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.

2.Make sure the remote system and your modem use the same communication parameters (speed, parity, etc.).

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 capability. Most IBM compatibles are capable of 19,200 bps under DOS and Windows. Operating at higher speeds under Windows requires a faster CPU (386/486 or better).

Modem experiences bursts of errors or suddenly disconnects while communicating with a remote modem.

1.Make sure Call Waiting is turned off.

2.Make sure the phone line does not exhibit excess noise.
