I have US Robotics Sportster ISDN TA. I have the UniLinx module for it. The module loads up fine and the card initializes fine because after I load them, the card rings when i call it. The problem is that I can't get it to dial out and start a PPP connection.
So if you have gotten a Sportster ISDN to connect, please tell me what software you used and exactly how you did it.
PS. My kernel is compiled with ISDN support.
