Entering "cmd.exe" as pre-command was an excellent hint, thanks for that
in advance.
results: the telnet command works and gets the packages via http.
unfortunately the cscript/wpkg.js combination did not work from the same
shell. (see attached screen capture)
i installed wireshark and even no packages were sent to http server when
executing cscript ....
