How to get l4android log on android_term?

hi, last mail, Stefan said

You can get the whole log by removing the log_term, and use core's LOG service for all children instead. Then all logs will appear on serial line. We've put the log_term in place in some run-scripts only for demonstration purposes, when there is no serial line available. For debugging it's often more convenient to use only the serial line.

By removing the log_term in l4android, I can see the log appear on serial line. How can I make the log on android_term appear on serial line? When I debugging, it is not convenient to use android_term. thanks. longjks
