NAME
       termio - System V terminal driver interface

DESCRIPTION
       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)](https://www.chedong.com/phpMan.php/man/ioctl/2/markdown) operations to get and set terminal attributes.

       The termio interface is now obsolete: POSIX.1-1990 standardized a modi-
       fied 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)](https://www.chedong.com/phpMan.php/man/ioctl/2/markdown) operations
       that  existed in System V.  (This was done because [ioctl(2)](https://www.chedong.com/phpMan.php/man/ioctl/2/markdown) was unstan-
       dardized, and its variadic third argument does not allow argument  type
       checking.)
