RS232=>PCI IC (That isn't proprietary): Does one exist?

[EyeMWing]

An idle curiosity has led to an offshoot of another project of mine. What's to stop me from taking my OBDII=>RS232 bridge board and slapping it directly on a PCI card with a few modifications?

Knowledge of the PCI bus, along with kernel drivers and user drivers? Unless you have experience with those subjects, be prepared to reboot your computer often. 🙂

Nah, essentially what I'm looking for is a plug-and-play serial controller. Anything that doesn't already have drivers and reference PCI implementations is naturally not worth the effort since the host system has a handy built-in serial implementation for me to exploit anyway.

There are plenty, actually. Google for "PCI UART". Note that PCI UARTs cannot possibly be _exactly_ compatible with legacy UARTs, simply because as a PCI device, they inherently are on BIOS-assigned I/O port addresses and use a shareable IRQ. Legacy UART drivers are not prepared for this.
