Try to disconnect your serial cable from DX, connect cable's RX directly to TX and type something. If you will not see echoes - something wrong with your usb2ttl, drivers or COMn settings. If usb2ttl works - try to take DX battery off, let it sit for a minute and connect it back.
PS: after fixing your serial ( I hope) - could you please attach the dump of uboot's "printenv" ?
