The usual way to go, as of any starting systems developer, would be to
attach a serial cable (rs232) to your testing machine and connect it to
your developers box, if the box doesn't have an rs232 jack, an USB to
R232 adapter will suffice. In order to see something you will need a
serial program like minicom, picocom, or even socat on your development box.
