Why exactly do you think you need to run stty and set the tty operating
parameters, when the bash process is quite plainly *not* connected to a tty,
it is connected to your C# application?
It's your application that is in charge of I/O - if it doesn't want echo,
all it has to do is discard the stuff it reads from the process' stdout
instead of displaying it, in your OutDataReceived/ErrorDataReceived handlers.

Don't do this. Win32 native processes don't understand Cygwin's tty
emulation, which is based on pipes.
