C++ getting data from serial/parallel port, how to?

Hi all:
I tried searching on the net, but I do not even know what I am looking
for. What I want to do is to write aprogram using C++ that will gather
data from an external microprocessor, format it and write it to a file
for later use. I can handle pretty much everything exept the part where
I "listen" to either the serial or parallel (may be USB?) ports for data
from the external source. Any help will be greatly appreciated.
