DSZ by Chuck Forsberg REGISTRATION $ 20.00
COMM JUL90 FORSBERG ZMODEM TERMINAL PROTOCOL
FILES: dsz0626.sdn
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.
