Interesting question you asked. I don't know how to activate a serial port other then enabling the driver if one is included in the kernel or manually install the driver. The best way to test if a device is working is to confirm the kernel detects it. The most widely used method is lspci.
In a terminal:
This lists all the devices on your system, with name, location, extensions and drivers.
Read this article to get a better understanding of kernel modules.
Bestly, just connect something to the serial port and see if it gets read.
