Here is a hint at least:


#include <stdio.h>
#include <sgtty.h>

getttyc()
{
	struct sgttyb status_in,status_out;
	int chr;
	ioctl(0,TIOCGETP,&status_in);
	status_out=status_in;
	status_in.sg_flags |= CBREAK;
	status_in.sg_flags &= ~ECHO;
	ioctl(0,TIOCSETP,&status_in);
	chr=getchar();
	ioctl(0,TIOCSETP,&status_out); 
	return(chr);
}

char *getttys(a)
char *a;
{
	while((*a++ = getttyc())!='\n');
	*a='\0';
	return(a);
}


Hope this is a help!
