RE: [Expectperl-discuss] Executing perl/expect script in backgrou nd.

[Blackstone, J. D. <jda...@ci...>]

  I couldn't seem to get Net::Telnet to work with Expect.  Any pointers?

  Alternatively, it has since occurred to me that just creating a socket (or
IO::Socket) would probably work just as well and would also avoid spawning a
process.

What did you try?  I'd create a new Net::Telnet object and use Expect-

Should work...

Yes, but then you would have to do the initial telnet handshake by 
hand, which is why Net::Telnet was written...
