Chapter 20 Pg 60 GSZ Reference Rev May-01-93 Typeset 5-4-93
21. 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 Omen's
TeleGodzilla (503-621-3746).
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 GSZ should show the same CRC values. ZIP uses a 32 bit CRC
compatible with the Professional-YAM and ZCOMM "crc" command.
pkzip -vt gsz
The following Pro-YAM/ZCOMM command gives the 32 bit CRC for GSZ.COM:
EXAMPLE: >>>c: crc gsz.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.
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 (503-621-3746)
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
Chapter 21 Pg 61 GSZ Reference Rev May-01-93 Typeset 5-4-93
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.)
May 3 1993: SlugBait should now work for XMODEM and YMODEM. Some
problems with file transfers over 7-bit paths were fixed (DSZ.EXE,
GSZ.EXE).
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 GSZ
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.
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
