RS232 toggole pins manually

[Zener_Diode]

Hey,

Is there an option to turn RS232 pins on and off manually (without an entire RS232 protocol) ?

Do you have any information/documentation about it?

Thanks ahead.

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?).

I want to use standart PC RS232 port.
How can I turn on and off signals there?
Where should I write the data (what is the base address and the offset)?

thanks ahead

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.
