Older machines, larger boxes may still have built in com ports exposed at the back, but most of us are living in the land of usb to serial.

surprisingly even the latest motherboards often have a serial header - pretty standard layout, it's the case manufacturers that don't provide the header. I believe there are headers out that that just replace one of the expansion card slot covers with a DB9/25 and plug via a short ribbon into the mobo header.

Another option I've seen used are boxes that connect serial via network (RJ11/45 one side, 9 pin t'other)
- really handy for connecting remote items (i.e. old manufacturing equipment) where there's already network cables/routers running nearby.
- usually have a web interface for setting the serial options as well as IP address etc (no need to fart about with dip switches)
- have a few different modes of operation... the easiest is it makes the device look like any other TCP/IP connection/stream (as a TCP/IP client)
- all the serial madness set/hidden in the web interface = (in above mentioned mode) no need to use for example the .Net Serial Comms API which [BTW, barely maintained] although not bad does have quirks - particularly if the device/cabling is a bit flaky or keeps dropping/closing the serial link.
