The ioctl are
ioctl(0, TCSETSF, {B38400 opost isig icanon echo ...}) = 0
ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0
ioctl(0, TCSETSF, {B38400 opost isig -icanon -echo ...}) = 0
and I think TCSETSF is the same as tcsetattr(0, TCSAFLUSH, ...) and that
"discard pending input" -- tty_ioctl(4). Note sure why the EOF follows,
but it's a clue.
Cheers, Ralph.
