Both possibilities would be fine for me: in one case we get X.31 support (which basically means write an X.25 stack) in the other case we would get active card support (which basically means write a generic CAPI interface driver and at least one hardware interface driver for your choice of an active card). Both tasks are everything but trivial, in case you would ask me what to do i'd recommend to add CAPI support to i4b, it seems to be not that much work to do as in the X.25 stack case and it gets us a bit further than that. hellmuth -- Hellmuth Michaelis Tel +49 40 55 97 47-70 HCS Hanseatischer Computerservice GmbH Fax +49 40 55 97 47-77 Oldesloer Strasse 97-99 Mail hm [at] hcs.de D-22457 Hamburg WWW http://www.hcs.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
