Parallel port program fail
1stly I'm not sure if I placed it in the right place, but anyway when I try to run the program in Win XP, it fails.
Any idea how to overcome this problem?
#include <conio.h>
#include <stdio.h>
int _outp( unsigned short port, int databyte );
// This program accepts an input from the user
// in decimal and outputs that number as an 8-bit
// binary number to the port at 378 hex, usually
// LPT1
int main () {
int inval = 0;
while ( inval < 256) {
printf("Enter a value in decimal (256 to quit)>");
scanf("%d", &inval);
_outp(0x378, inval);
}
_outp(0x378, 0);
return 0;
}
this is a simple program I gotten from the web too.
It gves an error.
