Hi, got "Parallel port complete" by Jan Axelsson but my edition is over 10 years now and only describes Win95 briefly. Is there any API support for using the parallel (printer) port on a low level, i.e. controling individual signal lines? I want to use it for controlling a custom designed test equipment hardware. Thanks Goran

They are available as Delphi/Builder components and are very easy to use. There is a trial version available so you can see if it works in your case. You can read and set each pin separately if you need to or treat it like a parallel port including the use of interrupts. It also has code to find all available parallel ports.
