Well, it depends on the hardware. The Grace card should be able to handle
multiple 56k modems without any problem, but PC-based systems have a problem.
DMA is needed, but there aren't enough DMA channels on most PCs to support
more than one high speed channel at a time. Perhaps a stripped AT might
be able to handle more than one PI card, once the driver is modified to
support multiple cards.
