So hir noch mein Prog: 
---------------------- 
#include "stdio.h" 
#include "conio.h" 
#include "iostream.h" 
#include "time.h" 
#include "windows.h" 

void Delay(long ms) 
{ 
DWORD time; 
time = GetTickCount(); 
do { 
} while ((GetTickCount() - time) < (DWORD)ms); 
} 


void main (void){ 

int z,i,j,ins,u,t; 
int z2=1; 
int nav=1; 
outp(0x378,0x00); 
cout<<"Wiederholungsanzahl : "; 
cin>>u; 
do{ 
switch (nav) 
{ 
case 1: 
i=1; 
j=128; 
for (z=0;z<8;z++){ 
ins=j+i; 
outp (0x378,ins); 
Delay(135); 
i=i+i; 
j=j-(j/2); 
} 
z2++; 
nav=2; 
break; 

case 2: 
i=128; 
j=1; 
for (z=0;z<8;z++){ 
ins=j+i; 
outp (0x378,ins); 
Delay(135); 
j=j+j; 
i=i-(i/2); 
} 
z2++; 
nav=1; 
break; 
} 
} 
while (z2!=u); 
outp(0x378,0xff); 
Delay(2000); 
outp(0x378,0x00); 
}
