'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
