MNP5 discussion... MNP5 only works if both ends support MNP5. MNP5's benefits are error correcting, and data compression. The data compression will work best with text files... precompressed files will actually take longer to download. If you have MNP5 you also have MNP2-4. MNP4 is the data compression part of MNP5. MNP4 you will actually get some speed improvements albeit extremely small, over normal transmission. Reason been no more errors and smaller over head. Speed up 0-10%, I'm just guess. Of course, if you're on a very noisy line the throughput suffers drastically... and the modem maybe fall back to 1200 baud... rest of the stuff I've read gets foggy... MNP5 bit old news anyways... I'm after V.42 and V.42bis modems... which have upto 4 times data compress and error correcting... MNP5 data compression is 2x sometimes more, sometimes less... but V.42bis doesn't suffer any when downloading pre compress files. Oh, V.42 is error correcting only... V.422bis is the one with both... it's the new standard for the true 9600 baud modems, too... 38.4K baud they're advertising now... or something like that... Yeah, forget MNP, go for V.42bis... Supra 2400+, Roger Coat's selling for $155. have to get one of those someday. Well, that all folk's... whitewolf@gnh-starport!info-apple
