   8 .SH NAME
   9 termio \- System V terminal driver interface
  10 .SH DESCRIPTION
  11 .B termio
  12 is the name of the old System V terminal driver interface.
  13 This interface defined a
  14 .I termio
  15 structure used to store terminal settings, and a range of
  16 .BR ioctl (2)
  17 operations to get and set terminal attributes.
  18 .PP
  19 The
  20 .B termio
  21 interface is now obsolete: POSIX.1-1990 standardized a modified
  22 version of this interface, under the name
  23 .BR termios .
  24 The POSIX.1 data structure differs slightly from the
  25 System V version, and POSIX.1 defined a suite of functions
  26 to replace the various
  27 .BR ioctl (2)
  28 operations that existed in System V.
  29 (This was done because
  30 .BR ioctl (2)
  31 was unstandardized, and its variadic third argument
  32 does not allow argument type checking.)
  33 .PP
  34 If you're looking for a page called "termio", then you can probably
  35 find most of the information that you seek in either
  36 .BR termios (3)
  37 or
  38 .BR ioctl_tty (2).
