In order to save less than $5 per unit, they move some or all of the processing power needed to run the modem into the host processor. There is no standard way of doing this. Some modems are almost fully functional, leaving only compression and/or error correction to the host processor. Other soft modems are little more than DSPs wired to the pci bus. These soft modems require lots of hand springs to get the proper signals out the right interface. There are many timing issues, if I'm told correctly, about when you need to do things. They really are nasty kludges that should be taken out behind the barn and shot in the head. Too bad they predominate so much. I'll take my PCI controller based modem over these aberrations anyday.
