after doing that you can play with hal driver.

Alternately, you can modify the system.stf file (in the syslib project's top-level directory) to point stdin/stdout/stderr to whichever device you'd like to use. The system.stf is mostly used for holding persistence for GUI settings on the syslib properties page. Cheers, - slacker
