On the X4U list (x4u at lists.themacintoshguy.com), I read of a cause for some of the modem connection/disconnection problems under OS X, and a solution. I thought I'd carry it over to this list, as some have had significant modem problems. Apparently under OS X and its later variants, it is possible to erroneously have multiple copies of modem scripts installed. People have found multiple copies under the following directories: /System/Library/Modem Scripts, user/Library/Modem Scripts, and/or /Library/Modem Scripts. People having these modem hangs, unwanted disconnects, and connection problems might want to look through their directories for multiple occurrences. I don't know where the proper location should be for the one desired script. Jerry
