Pride in ownership of what is rapidly becoming recognized as one of the finest V.34 modems available anywhere at any price, and the de facto modem "standard" by which many others are compared. * As of 6/20/95, items 25, 26, 27 are currently reported to be in beta trials. I cannot officially confirm that, but persons who have acquired pirated copies of USR's beta firmware tell us these things are there! Sure makes an awfully convincing argument to me to pick the Courier over the Sportster - kind of a no-brainer, assuming you can afford it. Yes, the Courier is expensive, but if you can afford steak why settle for hamburger? std. disclaimer applies - I do not represent my employer in this forum. -- Wolfgang Henke wolfgang@whnet.com . http://www.whnet.com/wolfgang WH Networks ... ftp.whnet.com /pub/wolfgang 2672 Bayshore Parkway Suite 503 ....... +1 415 390 9316 Mountain View CA 94043 ..................... fax +1 415 390 9317
