At the moment only some cards by German manufacturers are supported. These cards are the Teles/Creatix S0/16, the Teles S0/16.3 (actually, this is under development) and the so-called niccy cards from Dr. Neuhaus. > Has anyone else any experience with ISDN and BSD ? > I, and a number of others here in Gemany, are using it with good success. Of course, we're using the German cards. > Does anyone know of an internal ISDN card that mimics a COM port (as > modems do) ? > There's a number of them. Look at Dan Kegel's ISDN page. He lists a whole slew of cards there. There's even some company in the UK which makes an internal ISDN card that looks like a serial port.

Do you have all the documentation needed to write a driver which can talk to the board ? Like register descriptions, memory maps, etc. ? What does the board look like ? Is it memory-mapped, port-mapped, do you have to download code to it ? Lots of questions which can't be answered without more info. Linux supports lots of cards. Try looking at recent Linux kernel source. --- Gary Jennejohn (work) gjennejohn@frt.dec.com (home) Gary.Jennejohn@munich.netsurf.de (play) gj@freebsd.org
