The modem connects, Check that the modem is in data

but cannot pass data mode (“Data 9600”, for example, displays).

Check that the TD LED is lit on modem's front panel (steady or flashing) indicating that the modem is receiving data from the DTE.

If the modem is not in data mode, establish a connection with the remote modem.

•Check DTE for EIA signal requirements.

•Ensure the modem is correctly cabled to the DTE (with a straight-through cable for your electrical interface—V.35 or RS-232).

•Check that the correct communications port is being used.

Check the DTE rate of the local modem.

Check the DTE's flow control method.

If in normal mode, check for modem-to-modem flow control.

Verify line quality:

Ensure that the DTE rate matches the modem’s terminal rate setting.

•Ensure that the DTE's flow control is the same as the modem’s setting

(for example, XON-XOFF, RTS/CTS).

•If your communications software package’s file transfer protocol is used, and the package supports RTS/CTS Flow control, set Flow=RTS/CTS

(AT*FL3). If the package does not support RTS/ CTS flow control, set Flow=Off (AT*FL0).

Turn modem flow control off.
