It may be how the loadrt hal_parport cfg="X Y Z" assigns port numbers. I thought it might be parport.0 goes to the first address in the list, but apparently not. Maybe its the lowest address gets parport.0 and the next lowest address, parport.1, and so on. That's how I have used it so far, but I have always had my addresses in increasing order so I couldn't tell the difference. The 1 and -1 are a little funky. A 1 indicates that the function in this line should be executed first. A -1 means the line should come last. I believe you can use other numbers, like a -2 means the line gets executed second to last. I don't know what happens if you have more than one line with 1 or -1. At first I assumed the lines where executed in line order, but then I realized that there were some config files that had function call outs in more than one file, so the function execution order gets a little fuzzy. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC/EMC CNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending Craftsman AA 109 restoration Shizuoka ST-N/EMC CNC) ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
