    Communication over parallel port

    Hello everyone,

    I have a litle problem to solve. I have a code write in c that uses the parallel port to permit communication from one Pc to other over the parallel port. But that code has been done in Linux and now i need to do the same thing in Windows...

    The problem is that i can't find any library in Windows that permit the communication over the parallel port.

    And i have other problem... here is a exemple of the code in Linux


    /*Get access to the ports starting with DATA*/
    if (ioperm(DATA,3,1)) {perror("ioperm");exit(-1);}
    while (1) {
    error=0;
    control=DHIZ; /*control in known state: HiZ, NACK*/
    outb(control,CONTROL);
    /*printf("waiting for rdy assert\n");*/
    while ((inb(STATUS) & RDY) != RDY); /*wait for rdy assert*/
    printf("NEW:");
    fprintf(trace,"NEW:");

    I can't find the functions that do the same that the ioperm, outb and inb but in windows.

    Anybody can help me??

    PS: what is the tag to use to ident my code?

    PS2: sorry for my poor english...

    I believe most Windows compilers supply inportb() and outportb() functions.
    If you understand what you're doing, you're not learning anything.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    just one more question. What are the headers for that two functions? Can i use de Visual Studio .NET or i must use the Turbo C or something like that?
