I know you say you've tried minicom, but have you tried all the baud
rate/stop-start-bit combinations? By varying these you should be able
to find out the serial parameters that the screen is using. The screen
won't necessarily be outputting regular ol' ASCII though. I don't
know if minicom is cable of displaying output in hex, but according to
google GTKTerm (a hyperterm clone) is.
