Welcome to Lightning Z-Modem 1.01, this program is a breakthrough in transfer protocol! Many utilities today claim to boost your modem speed, but in reality they are not effective and in some cases they are hoaxes! Introducing our new L-Zmodem 1.01, this advanced state of the art lightning fast transfer protocol will save you $100's of dollars in modem upgrades! This is probably the LAST protocol you will ever need! It took 3 years of research and programming to create this protocol. WHAT IS SO SPECIAL ABOUT THIS ZMODEM ? ====================================== Regular Z-Modems will usually transfer at average between 1500-1600 CPS! Some Z-Modems will transfer even up to 1800 CPS! on a 14.4K modem! We discovered that Z-Modem protocol has built-in hidden features and it is actually possible to make use of this hidden feature. This makes L-Zmodem 1.01 compatible with *ANY* version of regular Z-Modem! This new transfer protocol will not only assure CLEAN error-free transfer but it will actually transfer at speeds 4-10 times faster than regular Z-MODEM !!! TECHNICALLY THIS IS IMPOSSIBLE ! ================================ When we first released this program, we got many letters from modem companies, individuals, companies and BBS System Operators telling us that this is all a *HOAX* and it can't be possible on a 14.4k modem !!! Of course we do understand that it is IMPOSSIBLE! The secret most people do not know is, the way L-Zmodem 1.01 operates! We are not about to reveal the formula, but we will explain to you the basics of how this all works. I'm sure you have heard of Fractal Compression ? No ? Well this technology was experimented a few years ago with no success as the compression technique would be too slow and often it would be almost impossible to decompress the compressed file also resulting in decompressed files being corrupt. We have worked upon this technology and improved it. We use special compression modules that work in conjonction with your V42 BIS and LAP-M modem protocols to provide the best compression possible. Not only that, with artificial intelligent realtime block-compression technique we are able to compress data a fraction of its size before being sent through the com port. We do not use only fractal compression here as it is mostly used as an experiment on image files. When sending a file through modem, the software will constantly ANALYSE the file being sent and determine the best compression method! Other complex methods are used also! AGAIN THIS SOUNDS IMPOSSIBLE! ============================= We have eliminated all the overhead associated with regular Z-modem! adding our own 16 BIT CRC check! Why not 32 BIT ? To save overhead time we have included another 16 BIT CRC check within the compression/decompression, all in 100% ASM code for fast operation! LET'S TALK RESULTS NOW! ======================= The importance here is NOT in the way L-Zmodem 1.01 works, it's the results it gives! L-Zmodem 1.01 will work as a stand-alone protocol from DOS, or can be used and integrated with virtually *ANY* terminal program or BBS software, easally, either using BATCH FILES or direct calls !!! It's not necessary for both parties to have L-Zmodem 1.01 installed, but the speed will be normal Z-MODEM! In order to assure 100% accuracy, an increased speed and a clean transfer, you HAVE to have L-Zmodem 1.01 installed on both end to assure compatibility ! Here's the results you can expect when using L-Zmodem 1.01 protocol in both ends. PLEASE NOTE: This transfer protocol will work ONLY with 14400 baud modems! set in V42 BIS LAP-M, and preferably clean lines! AVERAGE CPS RATE Regular un-compressed image, sound, 15000-20000 CPS documents, and other files (No mistake here !!) Results vary according to different file types Tightly-compressed .ZIP,.ARJ,.LZH 4000-7000 CPS and other compressed files The file is DE-COMPRESSED and re-compressed using our special module, all is done in realtime! NOTE: If both ends do not have L-Zmodem 1.01, for example the user has L-Zmodem 1.01, and remote has ZMODEM, then L-ZMODEM will transfer at regular ZMODEM speed since it is backward compatible with ALL ZMODEM protocol! There is no special knowledge needed to use this protocol, it is FULLY AUTOMATIC, and will detect if it's being used from DOS or on a BBS system! Always make sure you have your COM PORT BAUD RATE set at 57600 eventhough you have a 14.4k modem! STILL NOT CONVINCED ? ===================== Please do not think to yourself that a 14.4k modem cannot transfer at speeds more than 14.4k! The hardware part cannot of course. BUT HOW CAN YOUR L-ZMODEM PROTOCOL SURPASS THE 28.8k and even the 57.6K? ======================================================================== Usually the 14.4K V42 BIS modem has a throughout capacity of 57.6Kbauds! So how can data be sent FASTER ? Actually IT WON'T data will be sent at SAME SPEED! It's all in the way the data is sent. Please remember that when you get high CPS speeds, your modem technically is NOT running faster, it cannot, that's impossible, it is simply sending data differently, the data is being shortened before it's sent so it's sent in reduced size and de-compressed on the remote end. 30 DAY EVALUATION ================= You have an initial 30 DAY EVALUATION PERIOD for this unregistered copy. If you find this program useful, and I'm sure you will be convinced, then you must register! By registering you help us do more research and create new products to help boost performence of your computer. We are in the process of writing an integrated terminal program which will support L-Zmodem! You will receive a complete instructions manual and the registered copy which will include more features, a graphical display and the ability to SEND & RECEIVE files at high speeds, and will also include FAX capability!
