Don't you think it would be easier to use Perl with the Net::Telnet module?

Or if you don't want to use perl you could use expect/tcl. Shell scripting just isn't the right choice for what you are trying to accomplish.

Net::Telnet:
Net::Telnet - interact with TELNET port or other TCP ports - search.cpan.org


Expect:
Tcl/Tk - What is Expect? Why use it?
Using Expect
