- Rz and sz are Unix programs designed to support dial-in XMODEM,
- YMODEM, and ZMODEM transfers via the controlling TTY port.
-
- The contents of this archive can be uploaded to a remote Unix or
- Xenix system by ZCOMM or Professional-YAM using the supplied
- zupl.t script. Connect to your Unix/Xenix system, select an
- empty directory, and then give the YAM/ZCOMM command: "source
- zupl.t". This will upload minirb.c, compile it, and then use
- minirb to bootstrap upload the rz/sz files.
-
- Once these files are on your Unix system, you can type "make".
- The Makefile will list the various systems it knows how to
- compile the programs for, and the command to do so (e.g.,
- "make bsd").
-
- The Makefile is self explanatory; just say "make".
-
- Unregistered users can use our support hotline: 900-737-7836 at
- $4.69 per minute. Callers must be 18+ years of age. Registered
- users can obtain free support for problems not involving
- terminal servers or third party software using email or the
- regular Omen Technology phone number.
-
- Rz and sz work best with comm programs that properly support
- ZMODEM command and file AutoDownload (Pro-YAM and ZCOMM).
-
- The "GSZ" shareware program allows ZMODEM file transfers with
- DOS comm programs. GSZ provides a "mini term function" that
- supports ZMODEM AutoDownload. GSZ (part of GSZ.ZIP) and ZCOMM
- (ZCOMMEXE.ZIP, ZCOMMDOC.ZIP, ZCOMMHLP.ZIP) are available on
- TeleGodzilla and other fine bulletin boards.
-
- This software may be freely used to support file transfer
- operations to or from duly licensed Omen Technology products.
- This includes DSZ, GSZ, ZCOMM, Professional-YAM and PowerCom.
- Institutions desiring to use rz/sz this way should add the
- following to the sz compile line: -DCOMPL
- Programs based on stolen or public domain ZMODEM materials are
- not included. Use with other commercial or shareware programs
- (Crosstalk, Procomm, etc.) REQUIRES REGISTRATION.
-
- Rz ans Sz are Copyrighted shareware programs. Commercial Use of
- these programs is subject to licensing conditions detailed in
- the sz.c source code. "Commercial Use" includes use of this
- program to transfer files to/from any commercial or shareware
- program not published by Omen Technology INC. Please print the
- "mailer.rz" file, fill out the form and return same with your
- registration.
-
- 1.xx and 2.xx versions of rz and sz (April 1988) are Public Domain,
- but lack recent enhancements and bug fixes.
-
- The Man pages are formatted for those without Unix nroff. For
- best results, use less(1) (available on comp.sources.misc) as
- your manual page reader. Troff sources for the rz/sz man pages
- are included with copies of Unix Professional-YAM.
-
-
- FTP access is now available at ftp.cs.pdx.edu pub/zmodem
- directory. This account has the latest and greatest selection
- of OMEN files available for FTP. The files in this direcotryy
- are uploaded with ZMODEM directly from the Omen home system,
- preserving modification dates and file contents.
-
- June 22 1994: sz -e now escapes the all ones character (0xFF).
- Sz now understands receiver specified control character
- prefixing (ZCOMM/Professional-YAM zmresc string parameter).
-
- Apr 23 1994: Added -DOLD compiler flag for antique SYSV
- compilers without a standard /usr/include/stdlib.h header file.
- This causes rbsb.c to define char *getenv() etc. instead of
- getting these definitons from stdlib.h. You may have to fiddle
- with the declarations in rbsb.c #ifdef OLD to get a clean compile.
-
- Registration and support has been clarified and simplified
- (see mailer.rz).
-
- Feb 18 94: A bug in sz that caused constipation at the end of a
- file under certain options was corrected.
-
- Jan 27 1994: Minor bugfixes and improvements, documentation
- improved.
-
- May 16 1993: More bugfixes, POSIX support. Tested on SCO Unix,
- BSDI 1.0, and SunOS 4.1.2. Code simplified to avoid certain
- compiler brain damage. (Some complaints about redefinitons
- with some POSIX compiles.) (Void and Unsigned Long are required.)
-
- Jan 2 1992: Documentation on the sz -T command has been
- improved. Please use this command and Professional-YAM to
- diagnose file transfer problems before calling for support.
-
-
- VMS systems are now supported with native VMS versions in
- RZSZ.TLB. The rz and sz in RZSZ.TLB support wild cards and
- VMS record types.
-
- New for 1989: ZMODEM compression and other compatible
- extensions have been added to the rz and sz programs.
- Please read the comments in the rz.c and sz.c source code
- for licensing information.
-
-
- In order for us to handle problem reports, we must have the
- exact error messages displayed by Professional-YAM. If
- transfers do not work at all, we must have complete results of
- the sz -T test procedure! If you are not using an Omen
- Technology product to talk to rz/sz and have not registered
- rz/sz, contact the author of the communications program you have
- purchased for support. Some heavily marketed programs do not
- properly support the ZMODEM protocol.
