This sounds like you are trying to run activestate perl directly under
winnt. You sould look into cygwin, which gives you a pretty good unix
system on windows. Cygwin comes with its own perl and
pseudo-tty-emulation and IO::Tty and Expect works on it AFAIK, so
Net::Telnet probably will also work within cygwin.

Apart from that, what is running on the OS/390? Linux? Z/OS? If that is
the case, you should have rsh or better ssh capabilities. Then I'd do it
like this:

   open3(\*WTR, \*RDR, \*ERR, "ssh $os390host perl");
   print WTR $remote_script;
   while(<RDR>) {
     # process result line by line
   }

This spawns a perl interpreter on the remote host, sends it a script to
do some work (in that case, extracting some part of the huge file) and
reads back the result. No need to install something on the remote side,
no need for Expect.

Hope this helps.
