bidirectional IO that _doesn't_ take control from the user typing.
Well, no.  But you might try IPC::Open2 (I suppose you could capture
your prog's STDIN and feed it to the telnet process, and pass back
anything that is read from the telnet process's stdout handle).   Check
out Chapter 16 (Interprocess Communcation), section 3.3 (Bidirectional
Communication) of /Programming Perl/.  Since standard I/O buffering is
probably going to "ruin your day" (the Camel's quote), you might also
find IO::Select and the IO::Pty (avail on CPAN) module useful.

Hope this helps.
