NET+OS 7.5 CLI Telnet problem

I have a Digi Connect ME module with Plug-and-Play firmware and I can execute the following command :

set service range=5 nodelay=on

without any problems using Telnet session.
I have bought a Jump Start Kit with Net+OS 7.5 and I have developed a simple project including CLI Telnet service (with the project creation wizard). When I connect to device via Telnet, the command “set service” isn’t supported. Why ?
