This last line "can't access tty; job control turned off" means that
the shell has been started directly on /dev/console, which is normal is
you start a shell directly from an init.d script, because those scripts
are executed with /dev/console as the standard input, standard output,
standard err.
You really having *nothing* else on the serial line after what you
sent ?
According to your Buildroot configuration, your /etc/inittab should
contain a line :
ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100 # GENERIC_SERIAL
and you should see a login prompt on this serial line.
It's the /etc/inittab file that decides on which terminals a login
prompt should appear, by starting a getty program on those terminals.
What does your /etc/inittab look like ?
