So I _will_ have to upgrade to 4.0 pronto, then? I was sort of = hoping >I'd get round that, but ah, what the >heck.... :-) > Actually, -current would be better, but 4.0 has the newbus stuff, so it would be OK. The driver already probes and attaches the card fine, so you don't need to worry about that. What's missing is the dirty stuff - managing the FIFOs and tracking the state of the S0 bus (ISDN phases). The chip does not fit at all into the existing i4b way of doing things, so the driver has to do all the gory phase tracking itself. What I meant with "context of the next release" was that Hellmuth has split up the way that the layers interact. The new stuff is only in the developer's release of the code. You'd have to get ahold of that (not hard) and familiarize yourself with it before you could finish the driver off. Would take a while to get up to speed. I know that Hellmuth really wants to get this driver in before he makes the next release since the CCD chips are used on so many newer, inexpensive cards now. And they're pretty darn good chips, too. I'll clean it up a little and send it to you. May be a few days. Who knows ? Once I get started I may just finish it :) --- Gary Jennejohn / garyj@muc.de gj@freebsd.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
