			    ZCOMM
       Industrial Stength Communications Shareware(TM)

ZCOMM helps collect, control, and transmit information with a
minimum  of  time, hassle, and expense.  Concise commands and
unobtrusive displays facilitate telecommunications instead of
distracting.

When it comes to file  transfers,  just  remember  who  wrote
YMODEM   and   ZMODEM.   Two  decades  of  telecommunications
knowledge are distilled in ZCOMM.

ZCOMM's Full-Time  Capture  Buffer(TM)  saves  scrolled  data
other programs lose.  You can scroll, page, and string search
to cut and paste captured information.

Omen's Error   Containment(TM)  technology  minimizes  errors
caused by line hits and their effects on automatic scripts.

ZCOMM captures text with  many  choices  of  parity  bit  and
control  character  editing.   ZCOMM  can capture binary data
without protocols.   ZCOMM  does  not  limit  the  length  of
captured files.

Years of communications experience distilled in ZCOMM provide
rapid file transfers with unmatched reliability.  Unsolicited
customer testimonials chronicle accurate file transfers under
conditions  that  crash  the  other  programs, thanks to Omen
Technology's Cybernetic Data  Recovery(TM)  compatible  logic
enhancements and thorough protocol stress testing.

ZCOMM's protocols  are  more cost effective than the minimal,
unreliable XMODEM  support  available  with  other  programs.
They  are  easier  to  find and more useful than undocumented
proprietary protocols.

How often has your modem disconnected when  you  were  within
the  last few bytes of a long, expensive file transfer?  With
ZCOMM's ZMODEM file transfers, you can  resume  the  transfer
from  where  you  were  cut off, without wasted time or phone
charges!  And, if the transfer aborted because you ran out of
disk space, ZMODEM can recover from that too!

ZMODEM transfers files and  commands  with  a  uniquely  user
friendly  interface.   Unlike traditional protocols, only one
command or  menu  choice  is  needed  to  transfer  files  or
download commands.

A 32 bit Cyclic Redundancy Check, five  orders  of  magnitude
more  sensitive  than  CRC-16  and  billions  of  times  more
sensitive than XMODEM checksum protects your data.

ZMODEM provides high throughput with full integrity even with
timesharing systems, high speed buffered modems,  and  packet
switched  networks.   Unlike  other  "high  speed protocols",
ZMODEM's high speed does not compromise reliability.

Other ZMODEM  features   include   text   file   translation,
selective   transfer  of  modified  files,  and  remote  file
maintenance.  Security authentication* disables Trojan  Horse
attacks.  ZMODEM supports global operations by preserving the
exact  file  contents  and  modification  date, unaffected by
crossing time zones.

"Here's the simple  fact.   Zmodem  is  the  state-of-the-art
protocol  for  microcomputers.   It's the protocol of choice.
Forget the old dogs.  It's fast and bullet-proof."
	 -John C. Dvorak, INSIDE TRACK, PC Magazine June 1989

"without doubt the number one protocol"
                  -Boardwatch Magazine January 1990
