You have there a mistake. It is 'struct termios2', not 'struct termios'.
And for 'struct termios' it is more complicated as there are two
different 'struct termios'. One in file <bits/termios.h> (included from
<termios.h>) and one in file <asm-generic/termbits.h> (included from
<linux/termios.h>).
Function tcsetattr() uses 'struct termios' from <bits/termios.h> and
ioctl TCSETS uses 'struct termios' from <asm-generic/termbits.h>.
