I hope this isn't the wrong forum for this; I'm no kernel hacker. If this is inappropriate, let me know. I'd like to drive a lighting control system from the parallel port, preferably using the standard lpt driver. Question: Can I initialize the lpt device, i.e. pulse the -INIT output pin from user space (without having to change the driver)? This seems to be what the driver does on startup anyway, I'm just wondering if there's a way to reinvoke it later. If anyone could help, I'd much appreciate it. Please reply to me directly; I'm not on the hackers list. Cheers =8-} Mike
