I'm debugging a kernel module under VirtualBox with a guest and host OS as Ubuntu 10.10. I'm using the virtualbox serial port but I'm maxing out at the baudrate 115200. My grub config looks like this...

console=ttyS0,115200

Is there a way for me to change that setting in the guest OS so that the virtual serial port works at a faster baudrate? I've tried to use setserial. That didn't give me an error, but when I recompiled with a faster baudrate for the console I didn't see a change.

Thanks!
