Hi all,

Just thought I'd drop off some info that I rec'd from USR Tech sup.
X2 is meant as a replacement protocol FROM your ISP's X2 server to
YOUR serialzed USRobotics modem. When this protocol is active, it is
dedicated you will not be able to run other packets "in the
backround" (ie: FTP/TCP + surf the web + IRC + IPhone, check your
mail etc.) It will be sortof like the "old days" when you called your local
BBS system, (when the INterNET was still .EDU/.GOV/.MIL/.NET/.ORG)
found the file you wanted, selected z-modem! and waited until the
transfer was done.

So lets not get too hyped up about a free 57K connection. If your
looking for OPEN bandwidth, ISDN is still the best way to go.
