The only thing I see that may put the unit into some strange mode is
that your code below may have to be set in a different order like this.

If that does not work then it would be time to drop a scope to the
RXD and TXD pins between the LPC to make sure that there is data
transmitted and the RXQ1 is getting it. I when the check the RXD of
the reciever output of the RXQ1 to make sure that it is sending data
out from the transciver and that it is the correct baudrate and such.

Charles
