The following reply was made to PR kern/125756; it has been noted by GNATS. From: WATANABE Kazuhiro <CQG00620@nifty.ne.jp> To: bug-followup@FreeBSD.org, admin@lissyara.su Cc: Subject: Re: kern/125756: [sound] [patch] cannot detect soft-modem on HDA bus Date: Sat, 26 Jul 2008 13:59:30 +0900 Hi. We can treat a modem codec as one of the "function group" like the audio function group. But almost all the structure of the modem function group is vendor specific. To control the modem codec, we have to obtain the codec's specifications. But I don't know a manufacturer which offers HDA modem codec's datasheets. So it is hard for us to write these codec's device driver. Listing a modem codec in a verbose dmesg is not so an important matter (because we cannot use it now). FYI, last year I tried to port the "slmodemd" daemon which supports several number of modem codecs on Linux with the ALSA driver. http://homepage2.nifty.com/dumb_show/unix/slmodemd-FreeBSD.en.html I could get some responses from the modem codec. It generated sound which was similar to a dialing and negotiation tone. But I could not use it as a modem at all. --- WATANABE Kazuhiro (CQG00620@nifty.ne.jp)
