Terrific! Works! But... No pitch! e.g following code:
try it!

#include <sys/ioctl.h>	/* for ioctl() 	*/
#include <linux/kd.h> 	/* for KDMTONE 	*/
#include <sys/types.h>	/* for open() 	*/
#include <sys/stat.h> 	/* for open() 	*/
#include <fcntl.h>    	/* for open() 	*/
#include <sys/ioctl.h>	/* for ioctl() 	*/
#include <stdio.h>	/* for perror()	*/
#include <stdlib.h>	/* for exit()	*/
#include <unistd.h>	/* for close()	*/

int main( int argc, char **argv )
{
    int fd = open("/dev/tty1", O_WRONLY|O_NONBLOCK);
//    ioctl(fd, KDMKTONE, 0);


unsigned short msec = 100; /* This is for now ignored
*/
unsigned short freq = 450; /* The frequency of the
tone */

	for(int i=0; i<100; i++){
		freq += 5;
		/* Play sound */
		int rc = ioctl(fd, KDMKTONE, (msec << 16) | (1193180
/ freq));
		if(rc<0){
			perror("Error playing sound");
			close(fd);
			exit(-1);
		}
//		printf("%d ",i);
		usleep((unsigned long) msec + 1000);
//		ioctl(fd, KDMKTONE, 0);	// this here after
KDMKTONE makes a tick!
	}
//	printf("\n");
	close(fd);
	return 0;
}

What do we have to do to get the pitch variation to
work?
