You're right, that MNP5 and above require a license (Microcom has patents on some aspects of each of the higher classes). You can contact Microcom for information on not only the higher layers, but the lower layers as well. The contact is Greg Pearson, Microcom, 15303 Ventura Blvd. Suite 900, Sherman Oaks, CA 91403. Voice: 818-986-4212, email: 71330.1625@compuserve.com. CCITT Recommendation V.42 defines an "alternative protocol" in an annex which provides backward compatibility with MNP2-4. You can buy copies of CCITT standards from a variety of sources, including the UN bookstore in New York and the National Technical Information Service of the US Government. But I generally buy mine through Omnicom in Vienna, VA (1-800-OMNICOM). -- Toby ----------------------------------------------------------------------------- Toby Nixon, Principal Engineer Fax: +1-404-441-1213 Telex: 6502670805 Hayes Microcomputer Products Inc.
