You can do anything you want with RS232. It's little more than a specification of voltage and impedance.

It depends on the hardware that you're using (possibly a UART?).

The "standard PC" is available with many operating systems. Some of them only allow access to hardware through OS calls.

You probably need to consult the instructions for your developer's environment (VC, VC++, .net, etc.)

In computer, by default they are off.Particular application turns on the particular port.

In micro controller, by default UART is disable & you need to turn on when you require it.
