Can someone tell me how, in linux, I could get a tone
from the PC Speaker. In DOS or Windows, I would use
something like the following code:
void Sound(int, int);
main ()
{
Sound(1000, 100);
}
void Sound(int hertz, int duration)
{
unsigned divisor = 1193180L / hertz;
int portval;
portval = inb( 0x61 );
portval |= 0x03;
outb( 0x61, portval );
outb( 0x43, 0xB6 );
outb( 0x42, divisor & 0xFF ) ;
outb( 0x42, divisor >> 8 ) ;
sleep(duration);
portval = inb( 0x61 );
portval &= 0x03;
outb( 0x61, portval );
return;
}
The problem is, I'm not sure if I can just read and
output bytes from a port. Any alternate way would be
appreciated!
Thanks
