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
unstandardised, 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 tty_ioctl(4).
