Well, the prefered method should be to use POSIX termios when available.

http://www.opengroup.org/onlinepubs/9699919799/basedefs/termios.h.html

The sgtty.h from (e)glibc is the same as on Linux, just stubs.

On Linux:
checking termios.h usability... yes
checking termios.h presence... yes
checking for termios.h... yes
checking termio.h usability... yes
checking termio.h presence... yes
checking for termio.h... yes
checking sgtty.h usability... yes
checking sgtty.h presence... yes
checking for sgtty.h... yes

On kfreebsd:
checking termios.h usability... yes
checking termios.h presence... yes
checking for termios.h... yes
checking termio.h usability... no
checking termio.h presence... no
checking for termio.h... no
checking sgtty.h usability... yes
checking sgtty.h presence... yes
checking for sgtty.h... yes
