TX/RX pins

Guys, if my TX pin is not blinking (to transmit) when my jumper is at Xbee, what is the problem? :)

I configured my Xbee already but my serial monitor doesn't show anything.

Program is correct, uploading is successful

baudrate?

Baud rate is correct, even if it's wrong, they should show some weird readings on the serial monitor...but there is nothing :'(

However, like PaulS said, without the code we can't find what's wrong.

or maybe the wiring. "when my jumper is at..."
