When debugging code it can be handy to examine/alter variables and to check the state of input lines. So your main program can run and you have access to alter variables and run functions from a terminal. In this sample the main program is just a loop that flashes an LED. In that loop a periodic call is made to ShellTC which handles any commands from the serial terminal. The code is a bit quirky(it was originally written for a very resource limited device) but it works well enough to be useful, hence its published. More details in the main.cpp
