Baud rate mismatch on Xbee S1

I am currently facing a strange scenario in my project.

Controller baud rate 38400, Xbee S1 baud rate 9600
Miscellaneous characters are received to the controller

Controller baud rate 38400, Xbee S1 baud rate 38400
Nothing is received on the controller

What could be the issue?

incorrect wiring.
