I can connect gdb through /dev/pts/XX. My qemu is lanuched by

qemu -nographic -hda linux.img -kernel
./2.6.15.5-kgdb/vmlinuz-2.6.15.5-kgdb -serial pty -append "kgdbwait
console=ttyS0 root=/dev/hda sb=0x220,5,1,5 ide2=noprobe ide3=noprobe
ide4=noprobe ide5=noprobe"

Do you know where can I get the console output?

I would like to work out kgdb + qemu to debug linux kernel.

Thanks,
Neo

probably today we haven't the technology we are using!
