Chapter 19 Pg 59 DSZ Reference Rev Nov-27-93 Typeset 11-27-93
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 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.

PKZIP -vt 32 bit CRC: E83AEFB2 32864 gcolors.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 60 DSZ Reference Rev Nov-27-93 Typeset 11-27-93
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 (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
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 27 1993: Serial I/O has been tuned for more efficient operation
with internal modems using firmware driven virtual UARTs.
May 29 1993: The portx command now works with IRQ's up to 15, and,
optionally, nonstandard baudrate clocks.
EXAMPLE: dsz portx 3e8,15 rz -m
Newer UART chips can use raw bit rate sources higher than the standard
1.8432 MHz. Some 386 and 486 machines support MobyBaud(TM) operation
above 115200 bps.
To support a nonstandard bit rate source, multiply 5760 by the new raw
bit rate source frequency in MHz divided by 1.84320.
EXAMPLE: dsz portx 3e8,15,57600 sp 38400 rz -m
supports the 18.432 MHz clock option on the Boffin Electronics "WinSport
II" 2 port serial board.
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.
