Serial Port Terminal is a terminal analysis app that allows the user to view what a serial port peripheral is doing, relay commands to it, and log what occurs with that peripheral. It has a simple, unassuming interface and its logging functionality is quite thorough. On the other hand, it has few settings, meaning that its default implementation is what you will be doing with it and nothing else, and the software includes almost no documentation, meaning that the user must learn its (admittedly simple) interface and functions on their own.
