Can the serial port be used with baud rates beyond 115200?

What is the highest baud rate the serial port can be set to?
Did anyone manage to use the serial port beyond 115200?

I have successfully set the baudrate to 115200, but didn't manage to go beyond. I am running Debian Linux. When I changed the baud_base to 230400 using setserial, I was also able to set the port to baud rates up to 230400, but unfortunately communication is scrambled at that rate and even at lower baud rates that work with baud_base set to 115200.

The command I used to allow setting of higher baud rates was:

sudo setserial /dev/ttyS0 baud_base 230400
