it's very simple, just gcc and run it from console, I guess you should
quit X before running it, ctrl-c to exit:

#include <stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

int main(void)
unsigned char buf[10];
unsigned char last;
unsigned long counter = 0;
int fd = open("/dev/psaux", O_RDONLY);
if(fd == -1) { perror("couldn't open file"); exit(1); }
while(read(fd, buf, 1) != -1) {
if( (last == 0) && (buf[0] != 0) ) {
printf("\n[%010d] ", counter);
printf("[%03d] ", buf[0]);
last = buf[0];
return 0;
/* eof */
