Don't worry about online/offline, that only works with additional pins
wired and driven.  You do have a problem somewhere in your wiring, if
you are getting video output on the netwinder then it is _definately_
printing data to the serial port as well.

It is underneath the motherboard, undo the 4 screws holding the
motherboard in place to get at it.  RAM does tend to come lose every
now and then.

Serial driver might be compiled in.  Look in dmesg output for "serial"
or "Serial".  If possible, hook your minicom up to another PC until you
are sure you have that part working.
