hi  there is somme exemple of use of the parallele Port with inport ant
outport ;it work whel

#define PORTA     0x378   // 0x378 = LPT1   output 8 bits
#define PORTB     0x379   // inputs  4 bits ! some are reverse
#define PORTC       0x37a // port configuration


    outp(PORTA,0x1f);             // I   etat de depart sclk0_cs1();
    outp(PORTA,0x0f);             // I   debut de conversionsclk0_cs0();
    do
      {
        acq = (inp(PORTB) & MASQUE_DATA); // test fin acquisition
      }
    while( acq != 0x10 );
