i want to control around 4-5 digital pins using a laptop(without a native parallel port) so i thought i'd plug in a usb to parallel port converter and then it appeared like a generic parallel port on my machine (lpt1) so i used ouportb command to give it a byte of data but it wont just work. Either all the data pins are on at once or off at once.
Apparently it seems the converter is only meant for connecting a printer.
any help to toggle individual data pins(pins 2 - 9) of the parallel port will be appreciated
