Subject: Credit Card Dialing Procedures

Situation:
==========
You want to charge long distance faxes to your telephone credit card.

Solution:
=========
This document provides information on:

  - setting up credit card dialing in WinFax PRO
  - limiting credit card dial strings
  - calculating the maximum dial string for your fax/modem

Setting Up Credit Card Dialing
------------------------------
Note:   Credit card procedures may vary depending on your location. Check 
        with your credit card company for more information.

1.  Pull down the Fax menu in WinFax PRO, and select Program Setup.

2.  In the Program Setup dialog, click the Dial button to open the Dial 
    Setup dialog.

3.  In the Card Number field, type the credit card number against which 
    your faxing charges are to be made. Your card number appears as 
    asterisks.

4.  In the Comma Pause Time field, set the time in seconds that WinFax 
    pauses for a comma in the dial string. For many credit cards, the 
    optimum pause time to obtain a connection is 8 seconds.

5.  Some credit cards, such as MCI and Sprint, require a 1-800 dial 
    prefix, or other number. Type this prefix, if required, in the 
    Dial Prefix field at the top of the dialog. Include a comma at the 
    end of the prefix.

Note:   With a Unitel credit card, type the 7-digit access code and your 
        10-digit PIN number in the Dial Prefix field. Separate the access 
        code and PIN by a comma.

6.  Click on OK to save your credit card setup.

7.  When you are ready to send your fax, open the Options section of the 
    Send Fax dialog and perform the following:

    a)  Enable Use Credit Card.

    b)  Enable Use Prefix (if your credit card requires a prefix number).

    c)  Remember to include any normal dial prefix, such as "9," to 
        obtain an outside line. If necessary, add this prefix to the 
        credit card prefix you specified.

    d)  Type the fax number in the Fax field. Include the credit card 
        long distance access code in front of the number, and a comma 
        after the number.

        For example, in North America you might type ...

        01 23 789 555 6789, ... to charge an overseas fax.
        0 987 555 1234, ... to charge a standard long distance fax.

Notes:  If your version of WinFax is dated prior to April 21, 1993, do not
        use the recipient fax number variable (@X) in your header or cover
        page when sending credit card faxes. Upgrade to the WinFax PRO 3.0
        maintenance release to correct this problem. See the following 
        technical note for details:

          2074 - Delrina WinFax PRO Maintenance Release Patch

        If you select a phonebook record, do not include the credit card 
        long distance access code. WinFax adds the appropriate code to the 
        fax number automatically -- "01" for international faxes, and "0"
        for standard long distance faxes. If your credit card requires 
        different access codes, add the following lines with appropriate 
        codes to the [General] section of your WINFAX.INI file:

          CreditCardIntlAccess=
          CreditCardLongAccess=

        If you have an Intel CAS fax/modem, run the CAS setup program to 
        specify comma pause time. See your CAS fax/modem user documentation
        for details.

Limiting Credit Card Dial Strings
---------------------------------
The maximum dial string in WinFax is 42 characters, including dial prefix 
or credit card numbers. However, many fax/modems only accept dial strings 
of 38 characters or less. Lengthy credit card dial strings -- especially 
for international fax calls -- may exceed the maximum allowable for your 
fax/modem. When this happens, the message "No Dial Tone" appears in 
WinFax and the fax is not sent.

To shorten dial strings, omit spaces and hyphens in the credit card 
number, dial prefix, and fax number. Use single commas for pauses, and 
set the Comma Pause Time to 8 seconds or greater.

Note:   If your fax/modem init string contains "&F", and the comma pause 
        time resets to 2 seconds, add "S8=x" to the init string, where x 
        is the comma pause time in seconds. Upgrade to the WinFax PRO 3.0 
        maintenance release to correct this problem. See the following 
        technical note for details:

          2074  - Delrina WinFax PRO Maintenance Release Patch

Check your fax/modem user documentation or contact the manufacturer for 
details on dial string limitations. 

Calculating the Maximum Dial String for Your Fax/Modem
------------------------------------------------------
If you cannot find out the maximum dial string for your fax/modem, 
perform the following procedure.

1.  Start the Terminal application in Windows Program Manager. (Make
    sure that you are not running WinFax or any other communications 
    program.)

2.  Pull down the Settings menu and select Communications, then select 
    the COM port to which your fax/modem is connected.

3.  Click on OK.

4.  To test that your fax/modem is operational and communicating with 
    Windows, type ...

          ATZ

    ... and press ENTER.

    If your fax/modem is working properly, the following response appears:

          OK

5.  Type the command "ATDT" followed by 38 characters, for example:

          ATDT12345678901234567890123456789012345678

    This simulates the dialing of a 38-character fax number.

6.  Press ENTER.

7.  If you hear a dial tone on the fax/modem speaker, followed by the 
    sounds of the number being dialed, then the dial string is within 
    the fax/modem's limitations.

    If the fax/modem hangs, or a message such as "No Dial Tone" appears 
    on your screen, then the dial string exceeds the fax/modem's 
    limitations.

8.  Repeat steps #3 and #4, adding or removing a character from the dial 
    string, until you determine the maximum acceptable dial string.

    The maximum number of characters you can successfully add after the 
    ATDT command (up to 42 characters), is the maximum you can specify in 
    the WinFax dial string.
