I used the following command: depmod type=14 protocol=2 irq=10 io=0x580 id=teles I got this message: Teles 16.3c: IRQ(10) getting no interrupts during init 1 Teles 16.3c: IRQ(10) getting no interrupts during init 2 Teles 16.3c: IRQ(10) getting no interrupts during init 3 HiSax: Card Teles 16.3c not installed ! ISDN unloaded Any help? Gabor Csejtey
