-- Enable history
os.histrory(true)

os.logcons([enable])

Enable or disable Lua RTOS log to the console. If it's enabled log messages are displayed in the console and written to the /log/messages.log file if an SD Card is attached. If it's disabled log mesages are written to the /log/messages.log file if an SD Card is attached.
