Inconsistent behavior with standard input #22
Description
I have my simple console echoing script. (python3.12)
If I run this using pycharm's run configuration this works normally echoing the console input back to stdout. However any other running configuration fails. e.g) vscode, python3 my.py ... etc
However, if I use Path('CONIN$').open instead of os.dup any case fails with the same exception.

reader = asyncio.StreamReader(loop=loop)
with FileIO(os.dup(sys.stdin.fileno())) as fileInput:
# with Path("CONIN$").open() as fileInput:
transport, protocol = await loop.connect_read_pipe(
lambda : asyncio.StreamReaderProtocol(stream_reader=reader,loop=loop),
pipe=fileInput
)
try:
while not reader.at_eof():
line = (await reader.readline()).decode().rstrip()
print(line)
finally:
transport.close()
