Hi. I wanted to write programs that input and output ports to the PC Show.
In what way do these work?
How do I know about ports?
I do not know any information about the functions that work with the ports. I'll explain this.

In multiprocessing operating systems such as Windows and Unix/Linux hardware is a shared resource; applications do not have direct access to hardware. Hardware must be accessed by a device driver and then applications use devices using the device driver.
So you need to use the device driver for the port(s) and the documentation of it.
