Use this simple prog to cough up the scancodes:
#include <stdio.h>
#include <sys/kbio.h>
#include <sys/ioctl.h>
#include <fcntl.h>
#include <termios.h>
void die(char *str) {
perror(str);
exit(0);
}
int main(void) {
int err, mode;
struct termios term_saved, term;
int i;
char ch;
err = tcgetattr(0,&term);
if(err==-1) die("tcgetattr");
term_saved = term;
cfmakeraw(&term);
err = ioctl(0,KDGKBMODE, &mode);
if(err==-1) die("getkbdmode");
else printf("current kb mode: %d\n", mode);
err = ioctl(0,KDSKBMODE, K_RAW);
if(err==-1) die("setkbmode");
else printf("K_RAW mode set\n");
printf("Press Esc to end.\n");
err = tcsetattr(0,TCSANOW,&term); /* set terminal to raw */
if(err==-1) die("tcsetattr");
for(i=0; i<1000; i++) {
err=read(0,&ch,1);
if(err!=1) break;
printf("%d ",ch); fflush(stdout);
if(ch==1) break; /* break on Escape */
}
err = tcsetattr(0,TCSANOW,&term_saved);
if(err==-1) die("tcsetattr");
err = ioctl(0,KDSKBMODE,mode);
if(err==-1) die("setkbmode");
else printf("\nkb mode restored\n");
}
