The point behind the original post(er) was that winmodems will not respond to 
any of the COMx ports. Nor will the very small number of genuine com cards 
that use pci, but that's an added wrinkle.

THE major reasons for pci is to extend the crippled IRQ slots, extend dma 
beyond the 7 channel : 16 bit address range, and to provide better bandwidth 
than 16bit ISA.

Serial cards (modem or otherwise) fail on all criteria. They can only ever be 
8 bit, have no practical use for dma, and irq's 4/3 are welded to serial 
comms (but not the other way round). Thus the need to make a pci based 
genuine com card is not there and is more expensive to produce (more gold 
fingers).

Winmodems are an excellent idea if you have under-utilised cpu power. There's 
nothing illegal in using cpu crunch for dsp processing. Sound has been doing 
it for years (22% of your cpu useage can be spent processing wav files),  
prior to voodoo grafix engines (eg) so too for video. I don't like these cpu 
hungry devices philosphically, because I like things in lego-blocks, not an 
all encompassing cpu. But, I admire the cleverness and technology behind the 
winmodem.

If you accept the following:

1) an internal 'modem' is wasted on anything but ISA 
2) Motherboards will rarely supply ISA slots in future.
3) motherboards will ALWAYS have COM1 & 2' on board'

External modems are the *practical*, *permanent*, answer.
