You must set your lpt port addres for LPTx name. Use following program:
#include <stdio.h>
void setlpt(unsigned int num, unsigned int port)
{
unsigned int _offset;
if ((num == 0) || (num > 4))
return;
_offset = 6 + (num * 2);
printf("Setting LPT%d to 0x%X\n", num, port);
asm {
mov ax,0x0040
mov es,ax
mov di,_offset
mov ax,port
stosw
};
}
int main ()
{
setlpt(1, 0xEC00); //set LPT1 to be at 0xEC00
return 0;
}
