MNP is an error correcting protocol, and thus, will catch stray errors caused by noisy connections, et al. If you're talking with another MNP5 modem, you will also get data compression, which will, in most cases, at least double your throughput. At least this is what I am experiencing with my modem. Generally, I am pleased with MNP, and am glad I made the decision to purchase one.

Modem mfr's claim 100% improvement (480cps over a 2400bps line). MNP5 (or 4) totally eliminates line noise, too. Spend the extra bucks. -- Steve Dorner, U of Illinois Computing Services Office Internet: s-dorner@uiuc.edu UUCP: uunet!uiucuxc!uiuc.edu!s-dorner
