Suppose I wanted to implement MNP in software, rather than using a modem that provides it. This is ``real work'', so there would be budgets available. Who would need to be contacted to arrange any licensing? Where would I obtain the specification? Does anyone sell a version? Has anyone done this already? ian

You may also want to buy Microcom's documentation for $100 if you want a second reference (they're located in Norwood, MA). MNP5 and higher layers are covered by patents and other licensing restrictions owned by Microcom. I am aware of at least two companies who have already done MNP2/4/5 in software: MagicSoft in Lombard, IL (MTE) and SoftKlone in Tallahassee, FL (Mirror III). Also, I'm aware of a company in France doing an MNP 2/4/5 software implementation for Macintosh. Also, Greg Pearson of Microcom, the "father" (original designer) of MNP, has posted on Compuserve a "sample" implementation of MNP2 in C (source code); it is in the IBM Communications Forum libraries. -- Toby ----------------------------------------------------------------------------- Toby Nixon, Principal Engineer Fax: +1-404-441-1213 Telex: 6502670805 Hayes Microcomputer Products Inc.

I believe it was in the file PD2:<MSDOS2.MODEM>MNP.ARC at SIMTEL20, but I've never needed it myself, so I can't be sure. >>> Dan -- Internet: shad04@ccu.umanitoba.ca CI$: 72365,306 FidoNet: 1:153/511.1

Could someone either: - email a copy of this source code to me (either implementation) (are these sample implementations public domain?) - let me know how to retrieve one of these files (if it is possible for me to do so) - let me know where I could find out how to retrieve one of these files Thanks in advance for any assistance, -shawn
