Name
       cbreak, nocbreak - set/clear cbreak mode

Syntax
       int cbreak()

       int nocbreak()

Description
       The  routine  puts  the terminal into CBREAK mode.  In this mode, characters typed by the user are immediately available to the program and
       erase/kill character processing is not performed.  Interrupt and flow control characters are unaffected by this mode.

       The routine disables CBREAK.  In this case the terminal driver will buffer input until a newline or carriage return is typed.

       The initial settings that determine whether or not a terminal is in CBREAK mode are dependent on the terminal driver implementation.  As  a
       result  of this, it is not possible to determine if a terminal is in CBREAK mode, as it is an inherited characteristic.	It is necessary to
       call to ensure that the terminal is set to the correct mode for the application.

Return Values
       The and functions return OK on success and ERR on error.
