Summary: telnetlib on Windows: read_until() freezes

Initial Comment:
I'm currently trying to pass commands to a telnet 
session and get the texte generated (stdin + stdout) by 
the session. The problem I get is that the 
Telnet.read_until() function seems to freeze after a 
couple of command. I did a simplified script (attached) 
that reproduce the problem each time. In the script, 
when I send the command "echo bar7" to the telnet 
session, it freezes forever without a Timeout.

I'm using 2.3.4 on Windows 2000 Server. According to a 
feedback for the comp.lang.python newsgroup, this 
problem do not occur on linux systems.

Thanks

Yannick

Forget this bug. In fact it's not a bug. The problem comes 
from the fact that Microsoft does not use a *real* telnet 
server. It's documented in Perl Net::Telnet doc. They are not 
fully respecting telnet protocol.
