What do the debug level numbers correspond to in python's telnetlib? What is the maximum debug level? I've set numbers up to 400 without causing an exception.
https://docs.python.org/2/library/telnetlib.html#telnetlib.Telnet.set_debuglevel
As currently implemented, the only meaningful debug levels are 0 and > 0.
Basically, you can set debuglevel as high as Python's long datatype allows you to. However, it will not change debugging output past the initial 1.
