Subject: WinFax PRO 4.0 Enabling Release

The enabling release updates WinFax PRO 4.0 to include the following:

-  Remote Retrieval capability - If you have a Class 1 fax/modem, you can 
   poll remote fax devices to retrieve faxes. For example, connect to a fax
   information service to obtain up-to-the-minute international weather 
   forecasts. You can also poll your computer from remote locations to 
   retrieve faxes from your WinFax Receive Log folder. Password and Calling
   Station Identifier (CSID) checks ensure the security of polling.

-  Fax MailBox capability - When you subscribe to the Fax MailBox service, 
   you get a unique, private telephone number to deposit or retrieve faxes 
   and voice messages. You can call into this service from WinFax and 
   receive the faxes directly into your WinFax Receive Log.

How to Update WinFax PRO 4.0 from DOS Using DOSPATCH.BAT
========================================================

Note:  Be sure to EXIT completely from Windows before running the patch 
       files. DO NOT run DOSPATCH.BAT under a DOS session.

1.  Store the update files on a disk or on your hard disk, preferably in a 
    separate directory.

2.  Run the patch program from within the directory where the patch files 
    are stored and specify the location of WinFax.

        DOSPATCH {WinFax directory} 

    For example, if WinFax 4.0 is located in C:\WINFAX, run the following 
    to update the program to include Remote Retrieval and Fax MailBox 
    capabilities.

        DOSPATCH C:\WINFAX 

How to Update WinFax PRO 4.0 from Windows Using WINPATCH.EXE
============================================================
1.  Store the update files on a disk or on your hard disk.

2.  Start Windows.

3.  If you have the files on a disk, insert the disk into the "A" drive. 
    (If the external drive you are using is a letter other than "A", 
     substitute that letter for "A".)

4.   From the Program Manager File menu, select Run.

5.  In the Run dialog, type the following command line reflecting the 
    location where you stored the update files, for example ...

        A:\WINPATCH

    ... then click OK.

6.  In the dialog that appears, click Continue to update WinFax PRO 4.0.  
    Your software is automatically updated to include Remote Retrieval and 
    Fax MailBox capabilities.
