A lot of so called win modems perform far far worse than a real modem device because they move error correcting, MNP5 and friends onto the main machine.

You must be the only person they ever made happy

Unfortunately all the buggy 28.8's they've not fixed. They never fixed the dialin negotiation problem with Sonix modems they had either instead they expected the other vendor to work around it. As a happy irony 3com now own both USR and Sonix, tho they closed all of sonix down recently.

Incorrect. There are people who feed nothing but say 16KHz 8bit digital sample data onto their mainboard and do the rest of the work in the main machine. This is very rare in the PC world so far but extremely common in embedded applications.
