Hi, I installed my PC with dual boot (Windoz 2000 Prof.) and SuSE 7.1. Starting W2K my Fritz!Card works just perfect! However starting Linux and executing the command: isdnctrl dial ippp0 I keep getting the following messages in /var/log/message At SuSE support the told me that the cause message E011C has something to do with our ISDN TK!? Did anyone come across the same problem! How did you solve it? Looking forward to some clues!!! ++++++++++++++++++++++++++++++++++++++++++++++++++++++ Mar 19 18:32:28 linux kernel: ippp0: dialing 1 0W,,,,1056019951056...
