It seems STAC makes a version of its compression routines available for noncommercial use, (see www.hifn.com) as i live in Europe, i was not even able to get databooks for the chips they make ..... :-( Because of patent laws, not even rewriting STAC from scratch will help, since it it illegal. I doubt, there will ever be STAC compression available in any free PPP implementation. hellmuth -- Hellmuth Michaelis Tel +49 40 559747-70 HCS Hanseatischer Computerservice GmbH Fax +49 40 559747-77 Oldesloer Strasse 97-99 Mail hm [at] hcs.de 22457 Hamburg WWW http://www.hcs.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
