Based on my results with a USR V.90/X2 no-longer-a-"Sportster", the modem
and the PortMaster are happy to fall back (to about 28800 or 26400) if V.90
fails. I even saw it happen once on a "two-bong" connection, although more
often it's on a 4 bong or no bong one.

I'm using a Mac...it's quite possible you're seeing something Windows-ish
(with which I have experience only using VirtualPC, and then only when I
want to run PMConsole for some reason). And "my" central office is a
Flex-free zone in which V.90 works.
