====== Remote Serial Terminal ======
20.7.2016

This is a short how-to for using a serial terminal (minicom) via a ssh connection for controlling connected hardware and logging measurement data. 

===== minicom =====
minicom is a very simple to use serial terminal for the console.

The first run should be called with the parameter **-s** (setup). \\
Later you can call it without any parameter. It's main interaction is done with Ctrl+A Z. This opens the options menu. 

==== Important Commands ====
  * Ctrl+a l: define log-file
  * Ctrl+a z: options menu
  * Ctrl+a x: exit

===== screen =====
screen is a terminal based window manager. this is needed, to keep a remote 'minicom session' running, when the ssh-connection is closed

  * start ssh-session: ssh user@server-url.com
  * run: screen
  * press enter to close splash screen
  * minicom (start minicom in window 0)
  * do whatever you want to do in **minicom**. \\ to forward the Ctrl-a signal, which is catched by **screen** and very important for using **minicom**, use **Ctrl+a a**
  * before closing the ssh-session, the window must be **detached** with **Ctrl-a d**
  * you can close now the the ssh-session, and the minicom-session keeps running on the server. 
  * when you want to resume your minicom-window, connect to your server via ssh, and run
  * screen -r (for resuming the window)

==== Important Commands ====
  * resume last window: screen -r
  * detach window: Ctrl+a d
  * switch between windows: Ctrl+a 0-9
  * close a window: ???
  * kill a window: Ctrl+a k
