I think this is a two or > more persons projekt. Is there CAPI drivers for unix's? (Linux?) For Linux there is a CAPI interface available for the AVM B1 card (which already has sort of CAPI i/f onboard). As far as i remember it, there was a discussion in a newsgroup going on where some people wanted to add a general CAPI i/f to isdn4linux but i don't know if they did made any progress. The difficulty in producing a CAPI for BSD would be the lack of STREAMS in the BSD kernel(s) - when you have a look at CAPI 2.0 (or even CAPI 1.1) you will see that the Unix CAPI specification is STREAMS based, so before implementing a CAPI you will need to implement STREAMS. A CAPI would be a highly welcome thing, but i doubt we'll ever have one due to the huge amount of design and coding work necessary to get one. hellmuth -- Hellmuth Michaelis Tel +49 40 559747-70 HCS Hanseatischer Computerservice GmbH Fax +49 40 559747-77 Oldesloer Strasse 97-99 Mail hm@hcs.de 22457 Hamburg WWW http://www.hcs.de
