How to run two quartus_jli without blocking each other

I have two standalone fpga board.

I want force one board to send specific signal and hold about 10 sec and another board sample the incoming signal .

I have writen two jam files and work correctly at each board.

But when I open two cmd consoles and run two quartus_jli at each console.

The quartus_jli at second console is always blocked till the quartus_jli at first console finished it's job.

Are there any paramerters to make quartus_jli not block each other?

Or is the only way can work that to make a jtag daisy chain of two devices?
