So from what I gather, this is not output to the serial port when my
program outputs to the serial port, but when the system starts up right?
So, diag_printf () prints to the first serial port by default then
right?

I'm not entirely convinced about it's use now myself. When the TCP/IP
stack was new it was informative, but now we could make it optional.
For you, work around it by editting
net/tcpip/current/src/ecos/support.c,
in the function cyg_kmem_init().
Gary, any reason not to make a config option that controls debug output.
It could be a component that included other things like DHCP_CHATTER.
