Chapter 18 Pg 56 DSZ Reference Rev Oct-15-91 Typeset 10-15-91
19. CHANGES
Be sure to save your serial number/password (SNP) card and the putsnp
program you received from Omen Technology to use with future versions of
DSZ you may download! (Use GCOLORS to serialize GSZ.)
Current GSZ and DSZ versions are maintained on GEnie (IBM Roundtable),
EXEC-PC BBS, CompuServe (IBMCOM and CONSULT SIGs) as well as
TeleGodzilla.
DSZ is a popular program which has been the object of virus attacks.
Pirated/hacked versions of DSZ have cost users and DSZ's developer
thousands of dollars in lost time and other expenses, in addition to
injuring of Omen Technology's reputation.
Virus and Trojan code hidden in hacked/pirated copies of DSZ and
programs claiming to "register DSZ" have caused loss of data.

Your copy of DSZ should show this information as provided by
arc v dsz
or
pkxarc -v dsz
lharc v dsz
ARC, and LHARC use a 16 bit CRC.
ZIP uses a 32 bit CRC compatible with the Professional-YAM and ZCOMM
"crc" command.
pkzip -vt dsz
The following Pro-YAM/ZCOMM command gives the 32 bit CRC for DSZ.COM:
EXAMPLE: >>>c: crc dsz.com
If your copy shows a different CRC or file length, insist on a
legitimate copy and report the source of the bogus/pirated copy to Omen
Technology Inc. Omen Technology has received reports of serious
problems caused by unauthorized patches to DSZ, and cannot assume
liability for the performance of the resultant code.
Chapter 19 Pg 57 DSZ Reference Rev Oct-15-91 Typeset 10-15-91
COM7 and COM8 are changed; see the "port" command above.
A problem in the 1/17/89 and 2/2/89 DSZ versions corrupts files under
unusual circumstances. Please delete all instances of the 1/17/89 and
2-02-89 version.
There never was a "zmodem d" parameter in DSZ. Older versions of DSZ
ignored attempts to set this nonexistient parameter with a message that
humans ignored. DSZ now aborts when asked to set a nonexistient
parameter. There is a "d" parameter that controls time/date stamping of
files; Bulletin boards that need to disable time/date stamping of
received files should simply use "pd0" not preceded by a "z".
Good news for tired frog stompers! The ZMODEM rz/sz programs are
available in native VMS flavors with wild cards, record format support,
etc.. Pre compiled VAX/VMS files are contained in the RZSZ.TLB
compressed text library.
The DSZ and GSZ "t" command uses the DOS console driver for terminal
emulation. Standard ANSI.SYS is limited to a small subset of ANSI
escape sequences; NANSI.SYS, FANSI-Console and other replacement console
drivers provide faster screen updates and better ANSI terminal
emulation.
Oct 15 1991: To accomodate other vendors' programs which do not provide
a convenient way to control crash recovery, the "restrict" command
security check is not performed if the destination file exists.
Oct 8 1991: Some versions of putsnp were confused by a data pattern in
the Oct 7 dsz.com, misplacing the installed serial number. Oct 7 1991:
The "t" (talk) command now accepts -h and -H to enable local echo. Oct
1 1991: Fixed an interaction between FIFO uarts and YMODEM-g termination
after all files have been sent. Fixed problem of some options being
ignored on XMODEM and YMODEM downloads. Fixed graphics display problem
involving more than 40 MB of files. Sep 4 1991: GCOLORS now saves the
color scheme in a separate file GCOLORS.T. Many small improvements in
the GSZ file xfer display. GCOLORS adds a "m" menu choice to remove
color from the color scheme.
A conflict between crash recovery and user specified short packets has
been corrected.
DSZ.EXE and GSZ now accept the "c" option to force incoming files to use
a changed file name when a file with the same name exists. The
receiving program must support this new ZMODEM option or file
disposition will be undefined.
Aug 7 1991: Serial I/O modifications have solved a Wedge-O-Matic(R)
problem with one hardware configuration (antique 2400 bps internal
modem). Hopefully this will solve similar non-replicatable problems for
other users.
