+.SH NAME
+termio \- System V terminal driver interface
+.SH DESCRIPTION
+.B termio
+is the name of the old System V terminal driver interface.
+This interface defined a
+.I termio
+structure used to store terminal settings, and a range of
+.BR ioctl (2)
+operations to get and set terminal attributes.
+.PP
+The
+.B termio
+interface is now obsolete: POSIX.1-1990 standardized a modified
+version of this interface, under the name
+.BR 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
+.BR ioctl (2)
+operations that existed in System V.
+(This was done because
+.BR ioctl (2)
+was unstandardized, and its variadic third argument
+does not allow argument type checking.)
+.PP
+If you're looking for a page called "termio", then you can probably
+find most of the information that you seek in either
+.BR termios (3)
+or
+.BR ioctl_tty (2).
