Omen's artificial intelligence TurboLearn Script Writer^TM allows non programmers to automate logons and other repetitive procedures. Menu driven applications are easy to write in TurboDial^TM.

Professional-YAM is the only full featured communications program available for PC-DOS, WIN32, Unix, Xenix, SunOS, Linux, VAX/VMS, and OS/2.

"ZMODEM is the overall winner" -BYTE Magazine

"Professional-YAM showed the fastest file transfer times"-PC Magazine

Two decades of communications experience are distilled in Pro-YAM. Pro-YAM transfers files quickly and surely under real world conditions, not just across tabletops. Unsolicited customer testimonials chronicle accurate file transfers under conditions that crash other programs, thanks to Omen Technology's Cybernetic Data Recovery^TM logic enhancements and rigorous stress testing.

How often has your modem disconnected when you were within a few bytes of finishing a long, expensive file transfer? With ZMODEM-90^TM you can resume the transfer from where you were cut off, without wasted time or extra phone charges. If the transfer aborted because you ran out of disk space, ZMODEM can recover from that too!

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

"Pro-YAM's AutoDownload feature for ZMODEM and Kermit has got me completely addicted."

ZMODEM protects your data with a 32 bit CRC, five orders of magnitude more accurate than the CRC-16 used by Kermit and other protocols, and billions of times more sensitive than XMODEM checksum. ZMODEM provides high throughput and full integrity with timesharing systems, high speed modems, and packet switched networks. Unlike other protocols, ZMODEM's does not compromise reliability to get high speed.

Omen Technology's ZMODEM-90^TM extensions accelerate transfers and enhance flexibility. Pro-YAM's ZMODEM compression provides spectacular throughput increases on suitable files, significantly faster than other protocols tested with the PC Magazine Compressible Test File.

Other ZMODEM features include text file translation, selective transfer of modified files, and remote file maintenance (FILE SYNCHRONIZATION). A single command can update an entire directory tree, creating new subdirectories as necessary.

Security authentication disables Trojan Horse attacks.

ZMODEM supports world wide 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

"Without doubt the number one protocol" -Boardwatch Magazine

Competitors hype their undocumented proprietary protocols; experienced BBS operators know ZMODEM is the only high performance protocol that survives on the streets. ZMODEM's convenience, speed and reliability have made it the protocol of choice for bulletin boards, BIX, GEnie, Portal, Delphi, Unison, and other information utilities.

XMODEM: Lingua Franca for Legacy Programs

Pro-YAM supports Ward Christensen's XMODEM protocol with Cybernetic Data Recovery^TM and automatic file name generation. Omen Technology's exclusive Cybernetic Data Recovery transfers files under conditions that crash other programs.

• XMODEM CRC-16 is more accurate than simple checksum. But even with CRC-16, an error of just two bits can corrupt data sent with XMODEM. Cybernetic Data Recovery catches and corrects many errors that confound other programs.

• True YMODEM^TM batch file transfers preserve the exact file name, file length and creation date.
• XMODEM-1k and YMODEM-1k 1024 byte packets increase XMODEM throughput.

Pro-YAM supports Kermit with all the recent speedups without abandoning support for legacy applications. Convenient Kermit AutoDownload deciphers the sending program's Kermit dialect, saving keystrokes and frustration caused by dialect incompatibilities.

Swiss Army Knife for Protocols

• OverThruster^TM accelerator speeds XMODEM and YMODEM downloads
• Pro-YAM supports bulletin boards and traditional programs with Telink/FIDO, MODEM7 batch, WXMODEM (Windowed XMODEM), and SEAlink file transfer protocols.

Data Capture

Pro-YAM'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.

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

TurboDial^TM Scripts

Artificial intelligence TurboLearn Script Writer^TM technology brings script writing out of the guru's ivory tower and makes it accessible to non programmers.

Users who previously lacked the insight or confidence to write communications scripts are using YAM and TurboLearn Script Writer as "training wheels" to bootstrap their programming skills.

YAM's TurboDial^TM script language is the most comprehensive available. The unique ability to act on as many as twenty six events in real time permits real world unattended operation. Real Time pattern matches can trigger an immediate response or set flags that can be tested singly or in combination.

High level language features include if, while, and on conditions. Detailed debugging output and error traceback speed script checkout. Tests for time, carrier detect, parity errors and unprocessed keyboard and modem input give the programmer control of Pro-YAM's high speed communications functions.

Strings input from the keyboard, disk files, and the modem can be scanned, parsed, and analyzed with regular expression technology. The results can control script execution or be sent to the screen, disk files, or modem.

File related script commands check disk free space, file existence and length, and apply script subroutines to wild card filenames.

Exploiting Advanced Modems

User customizable dialing scripts fully exploit intelligent modems to provide dialing queues, alternate access numbers, MNP selection, baud rate fallback, and noisy line detection.

Pro-YAM's plain text Telephone Directory stores system names, port numbers, speeds, automatic logins, and message retrieval scripts, saving up to 400kb disk space per 100 entries.

Pro-YAM's Outcall Queue- allows unattended scripts to access information and place calls at scheduled intervals. The same modem can accept incoming calls between outgoing calls.

Controlling Information

Pro-YAM's Full-Time Capture Buffer^TM lets you scroll back and forth or search, scanning two hundred messages from bulletin boards in a couple of minutes. (It has to be seen to be believed.) To compose a reply, call your favorite editor (the one you've already learned!) as a subroutine without losing your place.

Transmitting Information

• Dual stack Command Recall saves your keyboarded host commands in a history file for search, recall, editing, and reentry.
• A rich palette of editing and timing modes permit file and message upload, even to fussy microcomputer Bulletin Boards.
• Remote access for file transfers and DOS program execution with baud rate detection and three passworded security levels.
• Outcall Queue intersperses scheduled outgoing calls with incoming messages on one modem line.

In a world where "hacker" means "antisocial", Pro-YAM provides important security benefits.

• Password Guardian^TM protects passwords with encryption.
• Working accounts and passwords can be protected with a master password which can be keyboarded or stored separately.
• Encryption programs protect data files with high security One-Time Key technology.
• Call-Back capability limits remote access to authorized sites
• Password/Call-Back protected dial-in remote access front ends local computers with baud rate detection and conversion.
• Pro-YAM rejects Trojan Horse attacks that penetrate other communications software.
• CryptoScript encrypted scripts limit dissemination of sensitive access sequences, prevent unauthorized script modifications.

• Pro-YAM uses moderately sized executable files without overlays. Conservative design avoids frustrating lockups and corrupted disk directories associated with other programs.
• "Flash-Up" Tree Structured Help Processor with 245k random access database
• 235 page typeset cross referenced manual with tutorials on installation, file transfer protocol selection, TurboDial^TM and script writing.
• Product support via phone and Internet.
• Demand Upgrade^TM gives quick access to updated versions with a simple modem call. Bug fix response time is a few days, not the months or years typical of other vendors.
• Site, Corporate, and Source/Trade Secret licenses available
• Supports several distinct flavors of "Half Duplex" systems.
• Pro-YAM Diagnostic Tools replace Data Line Monitors in 95% of applications. TurboDial scripts generate test stimuli and record results. Especially useful with laptop computers.
• Downloadable commands allow control by remote applications
• Logs callers, systems called, file transfers, and remote commands with time, filename, length, elapsed time, and speed
• Unix/Xenix flavors facilitate other work during transfers by minimizing CPU loading.
• Unix flavors arbitrate modems with UUCP
• Not copy protected
• Some features not available on all platforms

User Comments

"Before, I had said that anyone who can use any scripting program like Xtalk or whatever can use YAM (but there is a whole lot more to yam). Now, I would have to make a correction. Even if a user has never been able to figure out comm programs with scripts, YAM with tlearn now builds your scripts for you. It is easier and more idiot proof than any comm program with script capacity that I have ever used." -Jim Butler

"Xtalk is not nearly as flexible in its script language as YAM. I do lots of unattended file transfers at night from many different subdirectories on the local machine to various subdirectories on the remote machines. Lots of peculiar things have to happen, e.g., I rename incoming files if a file of the same name already exists, I append incoming data to preexisting log and data files, and so on. I've never dreamed up anything I couldn't get Yam to do. With Xtalk, I always felt I had to work against the program. With YAM, you work *with* it." -David McCune, The Proteus Group

"Can [other programs] handle regular downloading during your prolonged absence, say 3 weeks?" -Earle Robinson

"... I have *never* used any communications programs with protocols as bullet proof as those in Pro-YAM. Their implementation is the best I've encountered. Moreover, when dealing with a recalcitrant host (as only a VAX can be, sometimes), I invariably find myself at the command line of Pro-YAM."

"Under circumstances when *any* other program I've used - with the same protocol - would have tossed in the towel, Pro-YAM hangs in there. ... It's not just the protocol that counts...it's the implementation as well.

I've said it before, and I'll say it again. When the chips are down, and communications become vital, I'll find myself at the command line of Pro-YAM. Every time.

With any other program, I'll nervously go back and check the comm window from time to time. Not with ProYAM. I'll set it to run in the background, enable automatic logoff on completion of transfer, and forget about it. And *know* that unless Ma Bell breaks the line completely, I'm going to end up with good downloads.

There is simply no other communications program I've tried that's in a class with ProYAM. And I've tried most of 'em. -Dave Hoagland

"One thing I liked about the entire program was its documentation. At last I read something that didn't talk down to me and which wasn't over my head. It quickly explained the program to me and gave complete coverage to all its facets." -Mark Stern, OnModem Magazine

I use YAM a lot as a "general utility". Specifically, it has the the best "find" I've seen - you can do wildcard filenames, and YAM will scan them all, giving the name and line number of a match.

YAM, the commo package I use, supports ^W to be "word backspace" while typing. All these things are like oiling fine machinery, or putting a turbo 286 in your PC - they help PRODUCTIVITY. -Ward Christensen
