If no termcap entry is found for the type, the user is prompted for another

terminal type.

Once the termcap entry is retrieved, the window size, backspace, interrupt

Once the termcap entry is retrieved, the window size, backspace, interrupt,

and line kill characters (among many other things) are set and the terminal

and tab initialization strings are sent to the standard error output.

Finally, if the erase, interrupt and line kill characters have changed,

sets cooked and echo modes, turns off cbreak and raw modes, turns on

newline translation and resets any unset special characters to their

default values before doing the terminal initialization described above.

This is useful after a program dies leaving a terminal in a abnormal state.
