Yannick,

The parenthesis after the tn.close() did the trick. I know I've made
that mistake somewhere else. Telnetlib's documentation even clearly
says .close() and I bet they mean the () is required. Thank you!!!

As for read_until, I'm not reaching timeout there. I am however
setting a timeout in the statement like so:

  print tn.read_until("\n>",5)

Maybe that change is making it work for me. Did you set a timeout
value when you were testing?

I do have a problem with an expect, but I'm 99% sure a control
character in the stream is missing from my expect statement because
some of the strings are being detected. I'm going to play with it
again tonight.

I have to say I'm much impressed with the python language,
documentation, and community. It will take a while to understand some
of the doc as they are written in a very technical manner. I
personally think its great because most software efforts are plagued
by poor documentation. So far all my problems have been my own.

Thanks again for your help!

Mike
