You can open a serial port or parallel port by specifying \\.\COM1 or
\\.\LPT1 respectively (these examples open the first serial and parallel
port on the system, adjust the numbering as required).

For serial communication, you need to configure the port. Check out the
"Communication Functions" section of MSDN.

There are some "gotchas" when trying to use parallel ports. Google for the
rather lengthy "Parallel Port" thread in this group about a year ago.
