" Correct. PEP utilizes as much of the telephone line bandwidth as it can and, unlike V.32, can recover if the line quality gets bad and it has to fall back. V.32 will fall back to half-speed with a noisy line and then will quit altogether if things get worse. PEP can fall back in increments of 100 baud and can recover the speed if the line quality gets better. Once V.32 downshifts, it cannot recover. "The primary adavantages of the V.32 seem to be that they are better "for interactive use (I have several interactive users, and one of the "computers I call regularly has a couple of V.32 modems as well as a "Telebit) and they are slightly cheaper. " Telebit's work fine for interactive as well as UUCP/KERMIT/X/YMODEM. "Does anybody have any recommendations on what I should get? What kind "of UUCP transfer rates can I expect from each kind of modem? Is "anybody out there selling Telebits really cheaply? What about V.32 "modems? " T1000 in PEP mode: MAX=960cps, AVG=850cps T2500 in PEP mode: MAX=1920cps, AVG=1150cps V.32: I have no stats for these. -- Michigan Network Systems Technical Support Division 1-800-736-5984 BBS: +1 313 343 0800 E-MAIL: tech@mich-ns.Michigan.COM TELEBIT DIGIBOARD WESTERN DIGITAL 3COM SCO INTERACTIVE UNIX MICROPOLIS ADAPTEC
