I assume the info you need is not getting captured in /var/log?

Perhaps your system needs a firmware setting changed to use a RS-232 console?

I assume it is not waiting for a control line, e.g. carrier detect, to go high?

Some systems have buggy firmware and still read from the ps2 keyboard
even though they are printing to the RS-232 console.

If all else fails there is the aim a video camera at the screen method.  :-(
