V.34 faxmodem  (250-3037)          Operation           Faxback Doc. # 14477

TESTING YOUR MODEM

After the modem is installed, and power is turned ON.  Your modem
automatically performs a self test to verify the functionality and
integrity of it's hardware.  If an error is found, the modem sends an error
messages to the PC.  If you are using an external modem and an error is
detected, it is indicated by a flashing TM LED.

The following describe testing and the usage of modem commands.

1.  Make sure your modem is properly installed. 

2.  Turn ON your computer.  If you have an external modem, turn it ON as
    well.

3.  Run the communication software.

4.  Enter into the command or local mode.  Refer to communication software
    for more information.

ANALOG LOOPBACK TEST

1.  Type 'ATZ' - <ENTER>

    The modem should respond back with an 'OK' message.

2.  If you see "OK", or 0 (zero)
    Type  'AT&T1' - <ENTER>

    To enable the analog loopback test of the modem.  Wait approximately 5
    seconds to let the modem complete its handshaking.  Hold down one key
    e.g. "U", for a few seconds and watch the screen to insure that any
    other characters do not appear.

    If you do not see "OK", or 0 (zero), refer to Faxback Doc. # 14478.
    "Troubleshooting".

3.  Type '+++' and wait for one second to end the test.  The modem responds
    with an 'OK' message.

4. Type 'AT&T0' - <ENTER>

   The modem will respond with another 'OK' message.  Now you are ready for
   normal modem operation.

COMMON COMMUNICATION ERRORS

The following is a list of two common causes for errors:

1)  The most common error is that more than one adapter (such as: modem,
    serial card, and mouse card) is assigned to the same communication port
    address or the communication software is not configured to the same
    port that is set on the modem.  This can be corrected by verifying that
    no other adapter in the PC has the same port address as your modem.

2)  Some communication software may have automatic echo enabled.  In this
    case the display to the monitor will be duplicated (if an 'A' is
    entered at the keyboard, the monitor will display 'AA').  This can be 
    corrected by turning off the automatic echo of the communication
    software.

NOTE:  If you have problems running the test, check your serial adapters in
       your computer or refer to Faxback Doc. # 14478.
