Better yet, set up the serial port as a console, then attach another
machine via a serial line, and just have the 2nd machine log everything.
 Then you can use text tools to search through the resulting log file,
rather than having to dig through the paper.  Dig being the operative
word.  In the old days some of those crash events spewed garbage to the
printer, and that resulted in a ream of nonsense on the floor, and more
often than not, the paper mashed into an accordian behind a pinfeed jam.
