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 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) operations
that existed in System V. (This was done because ioctl(2) was unstan-
dardized, and its variadic third argument does not allow argument type
