Most parallel port plugs have the pins numbered, and the Linuxcnc parport driver's hal pin numbers correspond to that numbering. But if you need/want physical conformation, you can probe the parallel port pins with an LED adn use the parallel port test program to toggle the outputs watching for the LED to change.

Hello, I can test input bits with hal show, but how do I test output pins? That is I need to know parallel port physical pin positions in order to choose my pin schema and make a correspondence hal pin --> physical pin Thanks.
