Hi, > I'd like to squeeze a V.34 modem upgrade (any opinions on the USR > Sportsters for a home, primarily dial-out use?) out of the same ~$500 that I bought several pairs and have NOT been happy with them. I have to keep a fan on them to keep them from negotiating down and/or locking up, >From some mail I found on the net (author unknown): > 1. There most definitely is a "new" V34 USR Sportster which represents > a total, radical redesign over those V34 Sportsters which were the > subject of the rave reviews in the magazines last year. > > 2. This "new" V34 Sportster is currently in distribution with firmware > eprom dates of: > 09-19-95 > 10-13-95 > 10-18-95 > 01-11-96 > All of which have been observed to contain operational anomalies in > various stages of evolution. The major bugs in 09-19, 10-13 and > 10-18 firmware manifest themselves as interoperability and > connectivity problems, ie, inability to connect without placing > multiple attempts and a propensity to abort that connection once > made. They also have been observed to simply freeze up when trans- > mitting data. The freeze-up problem continues in 01-11-96 firmware. > > 3.

Latest known firmware available carries the date 03-04-96. -- Steve Passe | powered by smp@csn.net | FreeBSD
