HISTORY

  V1.53 (07/04/2000)

      New: Implemented new DTMF algorithm in Telephony/Answering machine
           to improve automatic fax detection and call transfer feature.

      Fixed: Under some conditions the Telephony/Answering machine crashes.

      Fixed: It was possible to access specific directories on the
             EFT server regardless of the assigned rights if a
             malicious EFT client uses relative paths to navigate.

      Fixed: The performance of the EFT server was bad with some third
             party EFT programs (e.g. BVRP software).

      Fixed: Fixed problem in EFT client when deleting files on after the other
             on a remote EFT server. A wrong file name was used after deleting
             the first file.

      Fixed: After a transfer timeout on slow systems the transfer is aborted
             and the file is not accessible (cannot be deleted, etc.).

      Changed: Improved robustness of EFT client and server application.

      Changed: The EFT client and server application display the wrong software 
               version in the connection info dialog box, if the remote site
               is also a Digi EFT application. 

  V1.52 (05/11/2000)

      New: Columbus World is now shipped as a self-extracting executable.

      Fixed: On Windows 2000 systems the CCM driver bluescreens
             if the driver verifier is enabled for all drivers.

  V1.51 (11/24/1999)

      New: Added installation of CCM and TSP to Columbus World setup.
           These files were previously installed by the card driver
           and/or the ISDN Tools setup. These files are automatically
           updated if they were installed before.

      Fixed: If a remote EFT application negotiated a window size of 1,
             the transmission stopped after sending the first block from
             Digi's client to the remote station.

      Fixed: If the user aborts a EFT file transfer, the next file
             transmitted started with data from the aborted file transfer.

      Fixed: It was possible to access the Settings dialog in the
             EFT client during a connection. If the dialog was confirmed
             with the OK button, the connection was terminated.

      Fixed: Columbus World does not install correctly on Windows 2000
             systems, because the OS was not detected properly.

      Fixed: The fax printer displays an "unknown format" error message
             when sending faxes on Windows 2000 systems.

      Fixed: In some configurations the EFT client displays an
             "invalid serial number" dialog box.

      Changed: The default charging factor in the german version was
               changed back to 0,12 DM in all applications.
