12F1840 config issues

Hi All
I searched for an answer to this but came up blank. The program has been reduced to a single serout2 command to test. It works fine on both a 12F683 and 16F688 with the correct configs but I cant seem to get it to function on the 12F1840. There is data out but its garbage and clearly the wrong baud rate. I suspect I have not configured something, probably the oscillator correctly so requesting help. Its probably obvious but I cant spot it.
Cheers Pete
