Get the output of a program in a file using QEmu

[Reng Zeng]

Hello,

It do NOT work for me, I add "#define USE_COM1_AS_CONSOLE 1 " into my
init.c, and run qemu by
     qemu -nographic -serial file:output.txt -boot a -m 128 -fda myimage.img
-hda fat:.

I did not get anything from output.txt. It run well in graphic mode, but I
want the output from the program.

I would appreciate if you could shed me some light on my mind :)

Thanks,
Alan
