Further to my earlier post. It pays to update only with "MacOSXUpdateCombo10.3.5.pkg" and not as I did last Thursday with the "Patch" only. Lloyd White is correct when he says he had no problem with his ISDN modem after updating. He probably used the combo update. I am now back to "normal" using my ISDN modem. It has been a very frustrating few days. Regards, Rod
