This is the code

Code:

#include <dos.h>
#include <string.h>

#define PORTADDRESS 0x378  /* Port Address Here */

#define DATA PORTADDRESS+0
#define STATUS PORTADDRESS+1
#define CONTROL PORTADDRESS+2

void main(void)
{
 char string[] = {"Testing 1,2,3                           "
		  "It' Works !                             "};
 char init[10];
 int count;
 int len;
 init[0] = 0x0F; /* Initialise Display */
 init[1] = 0x01; /* Clear Display */
 init[2] = 0x38; /* Dual Line / 8 Bits */
 init[3] = 0x1C; /* Shift the entire display to the right (aris) */

 outportb(CONTROL, inportb(CONTROL) & 0xDF); /* Reset Control Port - Make sure Forward Direction */

 outportb(CONTROL, inportb(CONTROL) | 0x08); /* Set Select Printer (Register Select) */

 for (count = 0; count <= 2; count++)
  {
   outportb(DATA, init[count]);
   outportb(CONTROL,inportb(CONTROL) | 0x01); /* Set Strobe (Enable)*/
   delay(20);                                 /* Larger Delay for INIT */
   outportb(CONTROL,inportb(CONTROL) & 0xFE); /* Reset Strobe (Enable)*/
   delay(20);                                 /* Larger Delay for INIT */
  }

 outportb(CONTROL, inportb(CONTROL) & 0xF7);  /* Reset Select Printer (Register Select) */

 len = strlen(string);

 for (count = 0; count < len; count++)
  {
   outportb(DATA, string[count]);
   outportb(CONTROL,inportb(CONTROL) | 0x01); /* Set Strobe */
   delay(2);
   outportb(CONTROL,inportb(CONTROL) & 0xFE); /* Reset Strobe */
   delay(2);
  }
}
