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
