title: Status line in C Terminal program
body: <p>I am running a terminal program written in c/c++ over shell.
  It is same like minicom for UART.</p>
  <p>I am looking for the way how I can create “Status Line on the bottom” same like attached picture (bottom line of minicom: CTRL-A Z line which is always there as a GUI).
  For sure it is not just printf/cout but needed some extended API, I guess.
  Has anybody done that? Or may be some idea how to proceed?
