Capturing console messages to a log

[BetterAuto]

I want to capture all console output such as debug messages and uncaught exceptions to a log file. I created the following code but it's not working. It does grab the console as expected. Also, if I comment out dupterm I can console.write("Some string") and it gets added to the log. But if I raise an exception it just quits the script without adding anything to the log. Please assist.

import time
from os import dupterm
from uio import StringIO
from _thread import start_new_thread

def log_console():
    console = StringIO()
    dupterm(console)
    while True:
        logH = open('/flash/console.log', 'w+')
        logH.write(console.getvalue())
        logH.close()
        time.sleep(1)

start_new_thread(log_console, ())

Edit: Oops, this question is almost a duplicate. Forgot that I had asked.

@BetterAuto: Did you find a working solution? I'm hitting the same problem.

Afraid not.

Check out sys.print_exception, that might be able to help with printing out exceptions and traceback
