What is a com port?

No modern gaming system needs an RS232 serial (COM) port. Motherboards tend to still include them for legacy purposes but the port is usually an unoccupied 9 pin header on the motherboard.

If your motherboard does not have one, it is no big deal. Like I said above, you will not need it for gaming.

I use com ports if I'm using embedded micro-controllers for various purposes - serial is still a very easy communications interface to use - just don't try and get large data in/out in a fast way.
As stated above - not likely to miss them.
