You should edit /etc/inittab (on the sdcard) to activate serial console,
something like:
----
T0:2:respawn:/sbin/getty -L ttyS0 115200
----

Doing so will make init run /sbin/getty for interactions on device
/dev/ttyS0, and you may need to adapt either or both of those choices
for your system. See also "man getty" if you want it log in
"automatically". It might be an issue that you may also get kernel
logging directed to ttyS0 as well; inspect /etc/inittab for turing
that off, if that's where the log listing is set up. Or possibly that
is a console parameter on the boot commandline.
