6.1 Troubleshooting
This chapter describes common problems in the installation, configuration and regular usage of
your Fax/Data/TAM Modem. To test the Fax/Data/TAM Modem, a communication software
package is needed and the package must include a mode that allows you to operate your
Fax/Data/TAM Modem by directly issuing internal commands to the modem.
Follow the procedures in the following sections to resolve these common problems:
No Response From Your Modem
1. If you are using the internal add-on card modems, make sure that the COM port address
you have set your modem to corresponds to the appropriate selection in the
communications software which you are using.
2. Issue the ATZ command to reset your modem. The returned result code should be "0"
or "K" depending on what communications program you are using. Your modem is OK
if you get one of these responses. If there is no response after issuing the ATZ,
continue to the next step.
3. Check if there are any other interface cards in your computer that use the same COM
port address as your modem. If so, you must set your modem to another COM port
address.
4. Issue the command: AT&F&W , if a "0" or "K" result code is displayed on the
screen, your modem is OK. Otherwise, contact your dealer for assistance.
Your Modem Does Not Connect After It Has Dialed a Phone Number
The problem may have several causes. The phone line may be too noisy or the telephone cord
may be poor. Try the line with a regular phone. Also the remote modem may not recognize
your modem baud rate.
You Can Transmit After You Have Connected to the Remote Modem
In this case, check the communication parameters of the remote modem, then configure your
software to the same number of data bits, stop bit, and parity.
6.2 Result Codes
The modem sends a response to the user via the screen after a command is issued. As shown in
the figure below, there are two forms for each result code: Modem Response code and digit
code.
