[] Anyone have any experience with Racal-Vadic 2400 baud modems? I am told the price to universities is $325. Is this as good a deal as it sounds? Jeffrey William Gillette Duke University

That is an excellent price. Would you let a fellow university in on the contaft at R-V? There has ben a lot of trouble with all of the 2400bps modems (the R-V "Maxwell" 2400 unit is included) based on the Rockwell chip set. It is most curious that these problems have not surfaced in Infoworld, or is it? In any event, there appear to be real prolems at 1200 bps talking to certain other modems. This has been notable on Compuserve in particular. R-V has been working feverishly for a couple of months now trying to extract better performance from Rockwell, buit no luck as of yet as far as I know. Note Hayes is in the same boat but doesn't talk about it, whil R-V lays their cards on the table. US Robotics does _not_ use the Rockwell chip set so is unaffected. I have been using a R-V 2400 unit for about two weeks,, mostly to here and CIS when at 1200 bps and have virtually no problems with it, so it may well be related to other factors such as phone line quality.

R-V and Hayes should be shipping modems with the bug fixed by now. Then again, maybe you're seeing modems that have been sitting on the shelfs for a few months waiting for a buyer. If you have a modem with problems, take it back! The bug is a publicly known flaw. -- Robert A. Pease {hplabs|zehntel|fortune|ios|tolerant|allegra|tymix}!oliveb!oliven!rap

I am curious as to the source of your information that Rockwell has fixed their 2400 bps modem chip set. I am in constant contact with two people who represent the equivalent of a beta test site for R-V 2400 bps units and as far as they know, no progress has been made in solving unreliability at 1200bps. Note that I have one of the Vadic units on loan and have never had significant problems at 1200bps - the trouble is related to the brand of modem on the other end, from my reports. -Charlie
