termio - 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.)
