The OPA0/tty00 and TTA0/tty01 serial terminals each provide a logging option.  Terminal logging is disabled by default.  Logging can be enabled on each terminal to a user specified file.  Terminal logging records everything entered and received by the terminal to a text file.  Care should be taken when using terminal logging, as the logs have the potential to become very large.  A fresh log file is created each time the emulator is launched.
