Error writing the following AT parameters

I have the XC09-038PKC-RA XCite 900MHz modems, I am trying to simply change the baud rate to 38400, it is currently set to 19200. any time i try to write anything using X-CTU it gives me an error and says “Error writing the following AT parameters -WR: connection timeout”

I have not been able to write any settings except an “xbee recovery” and reload the firmware, however this does not seem to change its baudrate…

Pleas help!

Try connecting to it via an RS232 cable with an RS232 port.
