Chapter 19 Pg 58 DSZ Reference Rev Nov-09-92 Typeset 11-9-92
20. 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 EXEC-PC BBS, BIX, GEnie
(IBM Roundtable), 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.
-rw-r--r-- 1 caf omen 52596 Nov 09 04:24 dsz.com
-rwxr-xr-x 1 caf omen 60007 Nov 09 04:20 dsz.exe
PKZIP -vt 32 bit CRC: 556570E0 52596 dsz.com
PKZIP -vt 32 bit CRC: 55BE2477 60007 dsz.exe
Your copy of DSZ should show the same CRC values. 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.
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 nonexistent parameter with a message that
humans ignored. DSZ now aborts when asked to set a nonexistent
Chapter 20 Pg 59 DSZ Reference Rev Nov-09-92 Typeset 11-9-92
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, available in the TeleGodzilla upgrade/vms
subdirectory, Compuserve VAXFORUM, GEnie, and other bulletin boards.
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.
DESQview users: make sure "Separate Shift State" is set to "N". (Tnx to
Tim Trott for this info.)
Nov 9 1992: Unwanted registration info message removed from registered
copies. Enhancements to accomodate non standard XMODEM programs.
Corrected spurious automatic recognition of hardware handshake
configuration.
May 3 1992: Recompiled to correct bad file size/CRC values in DSZ.DOC
and DSZNEW, pruned some unused code. No functional changes from April
27 vsn.
April 27 1992: The GSZWINDOW environment variable can be set to 1, 2 or
3 to leave the top 1, 2 or 3 lines unmolested. DSZ.EXE is compiled on a
newer compiler and now supports file sharing.
Bogus/hacked/infected files with early 1992 revision dates have been
reported.
Dec 13 1991: DSZ and GSZ automatically support Doorway 2.2 without extra
commands.
The RZ.BAT and SZ.BAT files are supplied for convenience. RZ.BAT allows
calling programs that emit an "rz" command to automatically start DSZ
from the DOS command prompt. SZ.BAT is a convenient command interface
that complements RZ.BAT. You may modify SZ.BAT and RZ.BAT with your
favorite options.
The GSZ file transfer display now shows a distinct color at the
locations where error retries occurred. This gives a visual impression
of the distribution of error retries.
Oct 15 1991: To accommodate 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 does not
exist.
