PR #38 added the setvbuf(_IOLBF) call in SimSerial's constructor but no test. Codecov reported full patch coverage only because the global Serial instance is constructed at static init, so the line executes without ever being asserted - a regression would ship green.
flush() was a no-op documented as "stdout is unbuffered at this level", which was untrue even before #38 and is plainly untrue now that the constructor sets _IOLBF. A completed line leaves on its newline, but a partial one - a prompt, a progress counter, Serial.print() with no trailing newline -- sat in the buffer until the next newline or exit.
Arduino's contract for flush() is "wait for outgoing data to be transmitted", so call fflush(stdout).
