That looks like a normal board-resident serial port, esp. with the "on acpi0" notation (which suggests that it is part of an ACPI-controlled device, and ACPI is ordinarily aware of only motherboard devices). It's likely part of the "super-io" chip, and it may possibly be connected to a 10-pin Berg header on the motherboard (or it may not be connected to the outside world at all). The motherboard manual, if available, might provide a clue.
