The problem is not whether the leds are blinking or not (in fact i can see the transmit led blink, but not the receive one). If she code should work correctly, i should have the keys pressed echoed back to the LCD -- which is not happening.

They would have to be really bright for you to notice them is they only blink a few times. Also the ambient lighting would effect weather or not you can see them.
