Appendix B - Enabling x2 in USR Products
With the exception of products shipped as x2, all U.S. Robotics products need to have
updated firmware installed and the feature enabled. The MP I-modem and NETServer I-
modem family of products need only to have updated software, they do not need to be
enabled. The method of obtaining that software, and enabling the feature, varies by
product.
Courier V.Everything (Analog)
1. Get the latest x2 code from http://totalservice.usr.com/upgrade/
2. Send the code to the modem using either SDL or an XMODEM file transfer.
3. Call U.S. Robotics host to enable x2.
4. Enter AT&F1S0=0&W
5. Turn the modem OFF and then back ON.
6. Enter ATI7 and look for x2 in the options:
Options HST,V32bis,Terbo,VFC,V34+,x2
Sportster
The only way to upgrade Flash-upgradeable Sportsters is to use the Flash Gordon utility.
The Flash Gordon utility is currently available through resellers.
Sportsters without Flash memory require a chip update which will require customers to
contact Customer Support using the Internet or by phone at (847) 982-5151.
Sportster 128 ISDN
This is not an analog-capable product and there are no plans for x2 support.
Total Control Quad Digital (and Analog/Digital) modems
