Hey guy -- don't be too surprised that a DSP chip can do a fancy protocol like V.32. Telebit has had this fancy modem out for a year or two now that does speeds up to 18.2 kbaud on normal phone lines, and uses a DSP chip as the main driving force. It woulda been nice if the two chips were the same, so that Telebit could liscense the software to NeXT, but it's too late now. Maybe the code can be ported? I can believe it. I have a Telebit at home. I *know* how nice it is to use 9600 baud and faster from home... :-) It's "unfortunate" that they chose to implement V.32 since PEP is such a nicer protocol to use. (smaller increments on the backoff for bad phone lines for instance, Telebits can make connections on lines so bad that most V.32 modems don't have a ghost of a chance, and error-correction built into the protocol rather than added on later with something like MNP). Now, the high speed modem market hasn't settled down enough to say that V.32 will rule the world. Telebit has been doing all the right things to both have their own niche market, AND to have their protocol accepted as a standard. Considering that Telebits are prevalent in University CS departments (lots of places took Telebit up on the half-price deal), PEP will be a common protocol available in the places where NeXT wants to sell machines. -- <-- David Herron; an MMDF guy <-- ska: David le casse\*' {rutgers,uunet}!ukma!david, david@UKMA.BITNET <-- <-- "Smarter than the average pagan god ...
