Then I don't really see the problem. When the test machine locks up, you 
download the trace to the workstation via the serial port (it's still 
in memory, and you control the snooper card via the serial line, which 
isn't locked up) and _after_ that reset the test machine. That deletes 
the trace from the snooper card's memory, but that's okay since it has 
already been copied to the development workstation for analysis.
