Win7 proffessional service pk 1. Parallell port does not work. i have set the port address as per the device manager, the port is enabled in the bios, on some systems this works on others with the same os it does not is there any address or settings in the registry i should be setting or changing.
i am using this port to drive something other than a printer. Device manager finds the port and an address is shown, however when i connect my breakout box which just monitors the outputs, the status differs from machine to machine consequently when running the same software one machine works and another does not. Does anyone think this may be a driver problem?
the output from the port is what is. Can this be changed or set in any wayother than changeing the address?
