It would seem, in theory, that a "winmodem" type of device could provide
better performance since it's data path into the system is across a
parallel bus and not through the serial port. Also, if the "winmodem" were
to DMA it's data into a region of memory and then interrupt the CPU, it
would seem that the system processor could get an interrupt per packet
instead of an interrupt per character...Just a thought....
