MS-DOS

= SUMMARY =

Omen Technology, Inc. has written an external upload and download protocol driver called DSZ. The driver supports Xmodem CRC, Xmodem 1K, Ymodem and Zmodem protocols and functions properly with Works version 2.00. The file is available for a small registration fee directly from the manufacturer at the following address:

Omen Technology, Inc. 17505-V NW Sauvie Island Road Portland, OR 97231

Modem: 503-621-3746 Fax:   503-621-3735 The current versions are also maintained on GEnie (in the IBM Roundtable), EXEC-BBS, and CompuServe (in the IBMCOM library).

= MORE INFORMATION =

To use DSZ with Works, you only need the DSZ.COM file in the Works directory. Since DSZ also needs to know the port to communicate through, the SET command can be used in the AUTOEXEC.BAT file. As an example, to set communications for the COM1 port, use “SET DSZPORT=1” (no spaces or quotation marks) in the AUTOEXEC.BAT file.

Use the following procedure to install DSZ for Ymodem downloads:


 * 1) Be sure DSZ.COM is available in the Works directory and the SET DSZPORT statement is correct.
 * 2) When running Works, choose the Run Other Programs from the File menu. Select the Change List option, then select Add options.
 * 3) Type “Ymodem Download” in the “Program Name:” field.
 * 4) Enter “DSZ rb” in the “Program Command:” field, then select Done.

Use the following procedure to install DSZ for Zmodem downloads:


 * 1) Be sure DSZ.COM is available in the Works directory and the SET DSZPORT statement is correct.
 * 2) When running Works, choose Run Other Programs from the File menu. Select the Change List option, then select Add options.
 * 3) Type “Zmodem Download” the “Program Name:” field.
 * 4) Enter “DSZ rz” in the “Program Command:” field, then select Done.

After establishing the connection with the host computer, select a file to download. When prompted for protocol, choose Ymodem or Zmodem. When the host indicates it is ready to send, choose the Run Other Programs from the File menu and run the appropriate protocol.

DSZ will report the status of the transfer and approximately how long it should take. When it is finished, there will be a “Completion Code” displayed, as well as a box instructing you to press a key to return to Works. If the Completion Code is zero, the transfer was successful; if the Completion Code is not zero, refer to the DSZ manual (DSZ.DOC) to determine the cause of the problem.

You can activate DSZ directly after running the “DOS Prompt.” This method is probably simplest for uploads because an upload file must be specified. Some hosts do not support true Ymodem and use Xmodem 1K instead. This will be detected by DSZ, but a local filename must be specified because it will not be transferred with the file. This will cause an error if the Ymodem Download option (mentioned above) is chosen.

For difficulties during file transfer and more options, refer to the DSZ manual for further information.
