USE_COM1_AS_CONSOLE=1 not effective

It seems that USE_COM1_AS_CONSOLE=1 is not effective for me. I'm
configuring RTEMS with this option (bsp: pc386) and as a result, in my BSP
install directory (specified by --prefix), I have:

*./i386-rtems4.12/pc386/lib/include/bspopts.h:#define USE_COM1_AS_CONSOLE 1*

However, when I run the hello example, nothing is output to the screen:

*qemu-system-i386 -kernel $(find . -name hello.exe) -serial stdio -monitor
null -nographic*

Below is a screenshot of QEMU, which suggests that both Console and printk
are  using /dev/vgacons. Does this imply that the USE_COM... is taken as
not effective?
And how should I correctly configure RTEMS to put the output to COM1 for
