Transmitted and/or received data contains errors.

Speed settings of the terminal device and the data module are not the same.

The local terminal device and the far end device are configured for different parity settings.

Far end data errors only during file transfer with PC data communication software.

Change terminal device speed to agree with the speed that was indicated in the C0NNECT nnnn message.

Change the parity setting of the local terminal device to match that of the far end device.

Disconnect the call, set the data metering option to off (see “Setting the Hardware Option DIP Switches” in Chapter 2), re- establish the call, and try the file transfer again.

The DATA LED is lit, but a CONNECT xxxx message or numeric result code was not displayed.

The display result codes option is turned off.

Turn on the display result codes option by typing

atq0 o [ Enter ]

The O command at the end of the above command line will cause the data module to return to the on-line mode and send the CONNECT xxxx message, or an equivalent numeric code, to the terminal display (see “Result Codes” in Appendix D).

Numeric code returned when CONNECT xxxx message is preferred.

The result code format option is set to numeric form.

Change the result code format option to message form by typing

atv1 [ Enter ]
