Using pipe in Windows Command line

Question

I'm trying to pipe a string into another command. The following snippet shows an example which does not work: It only starts Telnet, but does not "type" open 1.2.3.4 into the running telnet application.

echo open 1.2.3.4|telnet

How can I "write" open 1.2.3.4 after Telnet has been started?

(I know that there is telnet 1.2.3.4 - this is only a sample...)

Telnet in Windows is not scriptable. This free tool is.
