Even though my non-python telnet-server on the other side is sending #00-bytes,

My C++ implementation has no problems with this. I have to use Python 3.1 on
Windows.
I'm guessing this a known bug. What is the workaround? :(
Don't guess, search.

# Receiver
tn = telnetlib.Telnet()
tn.open(ip, port)
while 1:
response = (tn.read_until(b"\r",20))[1:-1]
Is there a reason that you throw away the first and last byte being
read? My wild guess is that the NULL is either the first byte, or most
likely the last, and then you throw it away.
if response.find(bytes.fromhex("00")) > -1:
It might be simpler to use a byte literal instead of calling a function
to generate a NULL.
if response.find(b'\x00') > -1:
print ("There are hex00 characters")
else:
print ("No hex00 characters found")
tn.close
Hope this helps.
