You need to connect the GND of the USB serial adaptor to the ground of the esp so that the serial communication is referenced to the same ground that the chip is using. It's a bit hard to explain but this is a good little starter: http://electronics.stackexchange.com/questions/38298/why-do-networks-need-a-common-ground-cable
Just add in another wire to join all three grounds together and it might work!
