}
c[i+1]='*';
outpw(port, c[i+1]);
printf("String is sent.");
getch();
}

void recieve()
{
int port=0x3f8,i=-1;
char c[100];
clrscr();
getch();
do{
i++;
c[i]=inpw(port);
if(c[i]=='*')
c[i]=NULL;

}while(c[i]);
puts(c);
getch();
}

void main()
{
int ch;
clrscr();
do{
printf("\n1.Send\n2.Receive\n3.Exit\n\n\tEnter your choice: ");
scanf("%d",&ch);
switch(ch){
case 1: send();
break;

break;
case 3: break;
default: printf("Wrong choice!!");

}
}while(ch!=3);
