In Version 2.2.1 and earlier, the TCP software for the network is loaded in a way that causes it to think that it needs to initialize itself. This was a reasonable thing when Version 2.2.1 was released, because network utilities like MacPPP were relatively rare. This behaviour was changed in V2.2.2. Mathematica now only checks across the network if your network software is already running. I would strongly recommend that you consider upgrading to the current version of Mathematica for the Macintosh. This version includes significant improvements over version 2.0 apart from improved behaviour with PPP and Slip software. Most implementations of SLIP and PPP (certainly InterSLIP and MacSLIP), there is an option which will not dial the modem if TCP has been initialized. Choosing this option should prevent Mathematica from dialing your phone. If this doesn't work, the only thing I can suggest for Version 2.0 is that you disable your PPP software when you want to run Mathematica. If you are interested in upgrading, write back to info at wolfram.com. I hope this helps. --Ian ----------------------------------------------------------- Ian Collier Wolfram Research, Inc. ----------------------------------------------------------- tel:(217) 398-0700 fax:(217) 398-0747 ianc at wolfram.com Wolfram Research Home Page: http://www.wolfram.com/ ----------------------------------------------------------- ==== [MESSAGE SEPARATOR] ====
