Try the following:
-----
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/ioctl.h>
#include <linux/keyboard.h>
#include <linux/kd.h>
void inskey (unsigned char *string, const char *tty_dev)
{
int tty_fd;
long kbmode;
tty_fd = open (tty_dev, O_RDONLY);
if (tty_fd_fd == -1) return;
/* The ultimate goal for this function is to be able to insert characters,
* as well as arrow key controls, even if the keyboard on the console is
* in K_RAW mode (as in dosemu particularly).
* For instance, at least, the insertion is not performed if in
* raw keyboard to prevent garbage results.
* Keyboard scan codes would have to be sent otherwise.
*/
ioctl( tty_fd, KDGKBMODE, &kbmode );
if( kbmode == K_XLATE )
while (*string)
if (ioctl (tty_fd, TIOCSTI, string++))
break;
close (tty_fd);
Then calling inskey( "ls -la\r", "/dev/tty1" ) for example should provide
the expected result on tty1.
Also you might want to use /dev/vcsa1 instead. See "man vcs".
