Hi,

I am using netcat to listen to a port and python to read stdin and print to
the console.

nc -l 2003 | python print_metrics.py

sys.stdin.flush() doesn=E2=80=99t seem to flush stdin, so I am using the te=
rmios
module.

while True:
   input =3D sys.stdin.readline()
   # do some parsing
   =E2=80=A6
   sys.stdout.write(parsed_data)
   time.sleep(3)
   termios.tcflush(sys.stdin, termios.TCIOFLUSH)


I am receiving this exception
termios.error: (25, 'Inappropriate ioctl for device')


I will be using this script on Unix based systems and I wondered what
approach I could use
to flush stdin?

Many Thanks

Aidy
