If that's not the case, then maybe we need _IONBF for stdin on JtR for the non-tty and non stdin cases too. I can't get a char from Johnny to JtR.

Mathieu, after you confirm the stdout change from Solar it would be good to test the stdin part to JtR. Go into the update method and write a character to JtR. and look for the update line from JtR. Then try with '\n'; after that try with fflush() on Johnny's side. Then we can proceed to trying the _IONBF on JtR side.
