I've been frantically trying to get information on modems for a system request going out tomorrow. I got the PC Magazine review of 9600 baud modems, but it just complicated things 8-)! That is it claimed the USR dual standard was terrible for bad line conditions, I had just about settled on USR until that. Is it true?? Also it didn't have reviews of Intel an Practical Pheripherals, two second choices. Anybody have any info on those? In reading this group I saw several references to Intel suporting V32.bis but no details, are they oferring upgrades? How much $$? Thanks for any info, Chuck@mitlns.mit.edu

For one thing, if you are talking about the December 1990 review of V.32 modems, remember that they only tested them in V.32 mode. As far as I've been able to tell from playing around with my Dual Standard, the USR implementation of V.32 is inferior to its implementation of the HST protocol. I consistently get better throughput at 9600 bps in HST mode versus 9600 bps in V.32 mode. It works great in HST mode over semi-noisy lines, I don't know about very noisy lines or in V.32 mode. If your primary criteria is V.32 compatability, I wouldn't reccomend the USR DS. You'd just be wasting most of the power, and other modems perform better in V.32 mode. However, if you want V.32 compatability and the extra speed of V.32bis, the Dual Standards are the only modems I know of that have that available right now. Finally, if you are just wanting to hook some computers together and never call anyone else, you could get some Telebit Trailblazers and transfer data at 19,200 bps.

How much $$? Although Intel has announced that they will have a V32bis upgrade for their 9600EX modem in 1991, they have not announced the specific date and the cost as of this writing. -- ..!uunet!m2xenix!armon!news news@armon.rain.com (Mehdi Attaran)
