dumb serial PCI cards are all supported. if not - few new lines in
pucdata.c makes it supported :)

USB to serial bridges is better and cheaper solution anyway.

PCI serials has classic primitive 8-bit chip, just bridged to PCI. some of
them are single chip - but internally are same. it means one interrupt per
every few bytes :(

anyway - can't your modem record at 11025 8-bit u-law or a-law? 16-bit
linear won't be better as logarithmic 8-bit is the way voice is
actually transmitted.
