Microcom Networking Protocol

Microcom Networking Protocol (MNP) family of error-correcting protocols were commonly used on early high-speed (2400 bit/s and higher) modems. Originally developed for use on Microcom's own family of modems, the protocol was later openly licensed and used by most of the modem industry, notably the "big three", Telebit, USRobotics and Hayes. MNP was later supplanted by v.42bis, which was used almost universally starting with the first v.32bis modems in the early 1990s.

Error correction basics

Modems are, by their nature, error-prone devices. Noise on the telephone line, a common occurrence, can easily mimic the sounds used by the modems to transmit data, thereby introducing errors that are difficult to notice. For some tasks, like reading or writing simple text, a small number of errors can be accepted without causing too many problems. For other tasks, like file transfers, even one error can "destroy" the entire file. As modems increase in speed by using up more of the available bandwidth, the chance that random noise would introduce errors also increases; above 2400 bit/s these errors are quite common.
