But those usb adapters can't do something the real rs232 or parallel port can do: directly interrupt and get processed within a known time, so much so as to sync clock to a GPS receiver. I wonder if you can connect two machines via parallel port cable and emulated port. -- Cheers, Carlos. ES🇪🇸, EU🇪🇺;
