Sort of correct.  AUX is a synonym for the output side of COM1.  If you were
to connect a terminal, serial printer or another computer running a
communication program to your COM1 port (with the appropriate cable),
windows would give you information about the FATAL EXIT it is making.
This includes the type of error and a stack dump.  Of course if you don't
have the symbolic stack information what you mostly get is a bunch of hex
addresses that don't mean much to you.

You can get fatal exit messages from the non-debugging version of windows,
though because of the additional error checking built into the debug version
you are more likely to get a fatal exit from it.

OX.SYS (notice how it sounds like AUX) is a driver that redirects the AUX
device to output on a monochrome montitor in a system that has both color
and monochrome displays.  It will not work on a PS/2 with both VGA and 8514
display adaptors.
