Description: This is a PCI card that provides two (additional) serial ports to a desktop computer. It has two 16550A UARTs on it, as well as some sort of controller chip.
I picked it up for $5.00 from a used computer/electronics parts shop, and I have no idea how old it might be, but it looks relatively 'modern'.

Pretty basic setup: I installed the card, then made sure that the kernel config had support for serial port(s), as well as selecting support for "other intelligent multiport serial controllers" but did not specifically select any of the sub-types offered because the card has less than 4 ports.
The driver used is called 'serial', so if you have that support enabled, you should have no troubles.
Upon booting, my AMI BIOS sees the card and identifies it by name in POST, and Linux assigns ttyS1 and ttyS2 to the cards ports.
Seems to work as it should.
