RCI Commands - How to send that?

Hi to all!

I’d like to know how to send something like that:

to my Digiconect ME, using RCI!

i have to type all in the telnet command line??Or I have to send a file with this inside??

I’m stuck here, and the only help I could get shows only serial commands, wich doesn’t fit my project…

The DigiConnect is on my lan, and the computer who sends
the command too.

Thanks!
