New release

DSZ  is  one  of  many  available programs that implement the
ZMODEM file transfer protocol.

DSZ's  ZMODEM  provides  advanced  file  management  features
including two levels  of Intelligent Crash  Recovery(TM), and
flexible  control   of  selective   file  transfers.     Omen
Technology's  Professional-YAM   Communications  Tools   also
provide security verified command downloading.

The ZMODEM file transfer protocol provides reliable file  and
command  transfers  with  complete  END-TO-END data integrity
between  application  programs.   DSZ's  32  bit CRC protects
against errors that sneak by "error free" modems and even the
most advanced networks.

ZMODEM safeguards all  data and supervisory  information with
effective  error  detection.    (XMODEM  and  many   recently
introduced protocols do not protect vital supervisory data.)

ZMODEM rapidly  transfers files,  particularly with  buffered
(error  correcting)  modems,  timesharing  systems, satellite
relays, and  wide area  packet switched  networks.   ZMODEM's
streaming    operation    eliminates    delays    caused   by
Kermit/XMODEM/YMODEM/JMODEM block  acknowledgements.   ZMODEM
eliminates  the  classic  XMODEM/YMODEM/JMODEM  PACKET LENGTH
compromises between transfer  efficiency and error  recovery.
ZMODEM's packet length is the entire file.

User Friendliness  is an  important ZMODEM  feature.   ZMODEM
AutoDownloadm   (Automatic   file   Download   without   user
intervention) provides a level of convenience unimaginable to
users of traditional protocols.
