Just a quick search in google will show you a multitude of suitable libraries for accessing the parallel port. Since there are no standardized protocol for communicating over the parport (except for printing), most applications access the parport by directly writing to port addresses. I am not sure how well the works with USB to parport adaptors. And since the parport is slower and clumsier than USB, proper software support for it is unlikely to emerge any time now. AFAIK there is no (planned) parport support in boost. Am 11.04.2009 um 05:45 schrieb master master:
Is there any library exist for opening parallel ports?
I know for serial it is "serial_port". I worked with it and it is working fine.
For parallel communication; which class(library) is needed..
