use the outportb() or outportw() function. 

/* writes a byte into port */
void outportb(unsigned chort portid , unsigned char data) ;

/* writes 16 bit data into port */
void outportw(unsigned short portid  , unsigned short data);


Remember to include the line :

#include <pc.h>


Hope this helps !
