Description:

The cfmakeraw() function sets the terminal attributes as follows:

termios_p->c_iflag &= ~(IGNBRK|BRKINT|PARMRK|ISTRIP|INLCR|IGNCR|ICRNL|IXON);
termios_p->c_oflag &= ~OPOST;
termios_p->c_lflag &= ~(ECHO|ECHONL|ICANON|ISIG|IEXTEN);
termios_p->c_cflag &= ~(CSIZE|PARENB);
termios_p->c_cflag |= CS8;

You can get a valid termios control structure for an opened device by calling tcgetattr().

Returns:

0: Success.
-1: An error occurred (errno indicates the reason).
