SyntaxError: invalid syntax (windows)

Gotcha, I got started from the telnet example listed in the docs. The linux 
install was via yum and installed 2.x instead. That explains it. Althought 
print (tn.read_all () ) runs in 2.x on linux.

I have another problem maybe you cna help me with. My telnet output 
jibberish in windows: I cna parse some of the output for results but is 
there anyway to get rid of the jibberish. (looks like hex but I'm not sure)

I can only use this tn.read_until(b'whatever string') Is this whats causing 
the output? the b switch. seems like I don't need it in linux. is that 
binary?

Thanks
