Re: Re: [ECOS] Problems with tcgetattr()

[Andre-John Mas <ajmas at sympatico dot ca>]

Just wanted to add a small correction, based on further tests:

If you set the 'Default console device' to be '/dev/termios0',
or any other termios compatible device, then your code can quite happily do tcgetattr() on 'STDIN_FILENO', since it is now mapped to the termios device. At least, this is how it is working for me :)
