I don't think that telnet is that simple. There is some hand shaking that
needs to be done before you will get a login prompt. Your best bet is to
read up on the protocol and go from there.

Or even simpler, use exec or system to run the telnet client on your
system and talk to it using a chat script...

By the way, why do you need to access this through telnet? There has to
be a simpler way!
