Andrew,
Thanks, I was able to get it configured on NT32's setup in Boot Maintenance
Manager->Console options and it prints purple output to the console
screens. Doing the same thing on the tunnelmountain box and setting the
"Console Standard Error Device Select" to the serial port options yielded
no output to the debugger. I am wondering if this is because the debugger
is already attached over the serial port UDK source debug ROM and the
standard error device cannot be set to this because of a conflict. Any
ideas on how to work around this and get standard error in this scenario?
