It means Jumper.

Pull those blue things off and you'll find 2 pins. Those blue blocks contain a bit of metal that joins the two pins together.

Typically it's for setting an option, but you'd have to look up the documentation to see what these are for. It *might* swap the transmit and receive pins, but it also may be for something totally different.

edit: I normally would recommend you start a new thread rather than reopening one from 7 years ago.

product description says 'Optional RTS and CTS handshaking functions'.Could it be for jumpers

It could be. It's definitely NOT for swapping the transmit/receive pins (and that only works for 3 wire connections - that this is not).

It's difficult to tell where the jumpers connect to, but I can see where they don't connect to :)
