B4J Question Calling external .bat - Files with params

How can i call an external proggi and give it the parameters ?
Cant get the COM-Part to work, no datas where sent.

Here ist the complete command line which works from Windows Command Line:
usbrelay.exe -c:5 -r:1#1

This switches Relay1 to on, with #0 its off.

But no plan how to include this in B4J.

I tested JShell already, but cant get any result.
