Parallel Port Access

Is there a way to directly access a PC's parallel port,
like the _inp and _outp functions in the standard library?
I'm trying to implement a simple IO function.

I've tried implementing functions in a dll using these,
but when I call these from managed code, my system locks
up.

Thanks in advance for the help,

Hello Peter,
Thanks for the help. I will look it over.

What I want to do is so simple, if I could use these simple IO
functions, but they must not be supported anymore. It appears that they
may not have been supported since Windows 95.

All I want to do is to send and / or receive a trigger signal to an
external device. I use these to make some basic timing measurements.

It may be possible using the CTS and RTS pins of the serial port and the
SerialPort.zip control.

Thanks again for the help,
Best Regards,
Dennis
