termios

[Victor V. Vengerov]

Hello,

The simplest way is to obtain current termios settings, set raw mode settings in
termios structure using cfmakeraw call and set new setting, e.g.


  struct termios tp;
  tcgetattr(fd,&tp);
  cfmakeraw(&tp);
  tcsetattr(fd,TCSANOW,&tp);

If you need some specific settings, you may do it after cfmakeraw.

Regards,
Victor
