Yep, very simple to do if the console is redirected to com0:
#include <fcntl.h>
#include <dev/isa/spkrio.h>
#include <sys/ioctl.h>
#include <stdlib.h>
#define FREQUENCY 2000
#define DURATION 50
int main(void) {
int spkr;
tone_t tone;
tone.frequency=FREQUENCY;
tone.duration=DURATION;
spkr = open("/dev/speaker", O_WRONLY, 0);
ioctl(spkr, SPKRTONE, &tone);
close(spkr);
return 0;
}
With a little effort you could make this so that you can define it on
the command line.
Or you could go by a previous suggestion and make it play a little
song by piping a text file into /dev/speaker.
