Hardware Input/Output ?

How can I read and write to any hardware ? Or the COM Port would be enough. Using VB .NET and Windows XP.
Thanks...

If you want to read/write to a COM port, you can use the Microsoft Communications Control - is a COM component not a .NET component. It is not in your toolbox by default, so you'll have to add it.

Is there any other way to read/write to a hardware device, or com port ? Not Using Microsoft Communications Control.

Thanks...

That I've never done, but I _think_ you would have to interface with the system .dlls - Windows API stuff.

I have a VB program controlling the Parallel port, you interested? in XP Pro.

See if this link does what you want. I found this cause I am going to make software to communicate with the GM OBD2 diagnostics to read trouble codes and the sensors in realtime.
