One of the most important commands I learned was "reset", especially when I was working with anything that would want to do something special. From the man page:
"When invoked as reset, tset sets cooked and echo modes, turns off and raw modes, turns on newline translation and resets any unset characters to their default values before doing the terminal described above. This is useful after a program dies a terminal in an abnormal state."
Except, it is also useful when you exit something like a Serial-Over-LAN session, after watching the BIOS do inappropriate things to your terminal window.
