telnetlib and NT vs. AIX

[dbeagle at my-deja.com]

I am trying to figure out what the difference is
between telnet to Windows NT and AIX.  As you can
see below the calls made to each telnet server
are the same but for some reason (unknown to me)
after I enter username in the NT telnet session
it never returns asking for the password.
Testing on the AIX system worked as expected. The
printout from both sessions is shown below.

Thank you for your help
