Yes and no. MNP level 1-2 is now in the public domain and MicroComm has release emulation source for IBM PC. A few hackers have made MNP lookalikes (which usually are even less compatible than the many lisenced ones :-). Still, the original MNP levels 3-10 are still property of MicroComm.... BTW: MNP is not a hardware protocol. Even if it usually runs inside a modem, it is still an implementation of an algorithm.... and MNP is as far as I know a SW implementation (written in C ?). If some modem companies will put it in micro code you might be right in calling it a hardware implementation, but not a hardware protocol as such. I don't believe there is any hard wired MNP implementations around (correct me if I'm wrong). I have thought about making a MNP driver for XENIX, but after getting MNP on my modem and finding out how useless it is (level 3), I abandoned the idea. Even level 5 is not very interresting for news transfers, since the news files are sent compressed and UUCP is a pretty good protocol ..... I've found that on good lines, MNP levels or V.42bis only makes the transfers of compressed files slower.
