Use CreateFile with "COM1", "com2", etc. Then just read/write using the file handle.

Parallel port (LPT1 etc) works exactly the same way, just use "LPT1" instead of "COM1"

good luck

accessing serial port or lpt port in windows is same as accessing a file. u can use CreateFile function in it insteady of file name use com1 or com2 whatever. see msdn help for more. also go through DCB structure and COMMTIMEOUTS structure.

Take a look here:

For parallel port you can use the same method.
