tak podla toho co som nasiel tak staci nastavit bit5 na BASE+2 na '0' a
datove linky su prepnute na citanie porom staci len citat z tohto portu
pi existencii signalu strobe (vysiela ho ustredna) ten mozes dat
napriklad na signal error (pin 15) ten je inverovany rovnako ako vystup
strobe. potom na citranie bude stacit nieco taketo:

---------------------------------
ioperm(BASE,3,1)			// vytvorenie pristupu k portu
do
	{
	while((inb(BASE+1)&4)==1);	// Cakanie na strobe signal

	putchar(inb(BASE));		// vypisanie prijateho znaku
	
	while(!(inb(BASE+1)&4);		// Cakanie na koniec strobe
while(1)
---------------------------------

dufam ze je to spravne uz som dlho v C nic nepisal :(

First they came for the Communists,
     and I didn't speak up,
         because I wasn't a Communist.
Then they came for the Jews,
     and I didn't speak up,
         because I wasn't a Jew.
Then they came for the Catholics,
     and I didn't speak up,
         because I was a Protestant.
Then they came for me,
     and by that time there was no one
         left to speak up for me.
