Re: [Expectperl-discuss] Connection Manager using Expect

[Roland G. <rgi...@cp...>]

Moving Expect objects between processes would mean moving open
filehandles between processes, which IS possible on some
architectures; but I don't know of a perl module that does that. This
definitively would have a lot hack-value, but I doubt that it warrants
the trouble... ;-)

So yes, your idea with a connection manager server seems the most feasible.=
..

Best regards,
Roland
