'uart' supports virtually _everything_ that 'sio' does -- plus an additonal chipset or two -- with precisely TWO exceptions. If it 'looks like' a standard serial port on the legacy ISA bus, and is based on the NS8250 through NS16550A, or a Zilog 'SCC', then uart works. The other alternative is a USB serial port. Even 'sio' support of "PCI serial ports" and/or modems was -very-limitid. precisely *two* models of cards -- The 3Com FaxModem PCI and the Advantec 56k Voice Messaging PCI FaxModem. Supporting serial controllers across a PCI bridge takes lots of work. and does *not* 'generalize' well. If I were in your situation, I'e look at a USB serial port and external RS-232 modem.
