In-reply-to: Message from Brian Somers of "Fri, 19 Dec 1997 02:22:57 GMT." <199712190222.CAA21792@awfulhak.demon.co.uk> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Date: Thu, 18 Dec 1997 22:44:03 -0600 Sender: owner-freebsd-questions@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk Reporting the initial connect speed isn't very useful. I suspect modem makers *know* the initial connect rate is the only thing most users will ever know about the negotiated rate. When I last purchased a modem I paid about $50 extra for a SupraSonic 28.8V+ with 2-line LCD display. I had a Supra FaxModem 14.4k before, with 2-1/2 digit display. These days I almost always get a 31.2k initial connection for receive. 26.4k is typical for transmit. The receive rate always negotiates down to 28.8k about a minute into the connection. That's where I'm at now, T26.4 R28.8. Transmit rates almost never change. T24.0 is common. I suspect my modem isn't going to bother negotiating a higher rate (and increased errors) when it rarely saturates the rate it has. When I have seen it change TX rate was during uploads. What would be nice would be an out-of-band data channel to the modem for discovering this information. Probably would be easier with an internal modem than external. However I'd be happy to use two serial ports to get the info. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
