The receiver seems to receiving a continuous stream of three bytes -Which would be a bitstream of '1000 0100 0010 0000 0000 1000' ignoring start and stop bits and idle. It looks to me like a pulse is being repeatedly sent, or there's a baud rate or polarity mismatch.
Possibly a wiring error but I have no real idea. I would suggest simplifying your sending code to -That sends one byte every second. See what that shows on the receiver.
