I dont think it's possible to obtain the speed you ask on the host CPU, but
with the addition of a "black box" dedicated to doing the error detection and
correction it may be achieved.  Multitech offeres MNP level V in their modems
as I'm sure other manufacturers do- if you arent going through a modem, there
are manufacturers of such devices for direct connect lines (Black Box Corp,
etc).
