The german USR branch actually provided documentation on the Sportster card to (at least) Hellmuth and me. Back in those days neither AVM nor Teles would give away any information about their cards, not to us and not to the Linux people. There was "common knowledge" how their cards were designed floating around all over the ISDN scene, I guess most people looked at the provided DOS drivers. And actually, those cards are pretty simple, once you figure out their register mapping and any additional reset/config tricks. Later AVM made up their mind and became more open, AFAICT Teles never reached this stage. Later, when ISA PnP cards became common, register mapping was easy to guess form the PnP info, and most drivers probably were done by trial & error. Martin
