       termio - the System V terminal driver interface


       termio is the name of the old System V terminal driver interface.  This
       interface defined a termio structure used to store  terminal  settings,
       and  a range of ioctl(2) operations to get and set terminal attributes.

       The termio interface  is  now  obsolete:  POSIX.1-1990  standardized  a
       modified  version  of  this  interface,  under  the  name termios.  The
       POSIX.1 data structure differs slightly from the System V version,  and
       POSIX.1  defined  a  suite of functions to replace the various ioctl(2)
       operations that existed in System V.  (This was done  because  ioctl(2)
       was  unstandardized,  and  its  variadic  third argument does not allow
       argument type checking.)

       If you’re looking for page called "termio", then you can probably  find
       most  of  the  information  that  you  seek  in  either  termios(3)  or


       termios(3), tty_ioctl(4)
