Subject: "Not Enough DOS Memory To Communicate With CAS"

Situation:
==========
Periodically, the message "Not Enough DOS Memory To Communicate With
CAS" appears when using WinFax with an Intel CAS fax/modem.

Solution:
=========
This problem usually occurs when there is less than 575 kilobytes of 
conventional memory available on your computer.

To verify your conventional memory resources:

- Exit Windows and go to DOS.

- Change to the command line for the DOS directory, then type ...

    MEM

  ... and press ENTER.

- A summary of your computer's memory resources appears on the screen.

Try any or the following measures to solve the problem:

a)  Update to the April 21, 1993 release of WinFax PRO 3.0 if you are 
    running an earlier release of the software. The updated release 
    reduces DOS memory requirements, which may solve the problem. To 
    verify the release date of your software, pull down the Help menu 
    in WinFax, and select About. For details on updating, see the 
    following technical notes:

        2074 -- WinFax PRO 3.0 Maintenance Release: April 21, 1993
        9002 -- Downloading and Running Patches for Delrina Products

b)  Rearrange the order in which memory resident programs such as device 
    drivers and TSRs are loaded. For example, if SHARE is normally loaded 
    first followed by SMARTDRV, load these programs in reverse order. 

    For complete details on loading memory-resident programs, see your 
    DOS user/reference manual.

c)  Free up conventional memory by loading resident device drivers and TSRs 
    into upper memory and optimizing expanded (EMS) and extended (XMS) memory 
    allocations.

    For complete details on memory management, see your DOS or memory manager 
    user/reference manual.
