According to table 10-8 in the data sheet you should set tris bit to 1 for both tx and rx, I have never needed to do this before but it might be worth a try. If it still doesn't work I suggest you keep tris bits set to 1 if you try other things.

Tried that initially. Worked on USART2 but not on USART1, so i tried setting TX to output but no change. As far as i can see there is no reason why it should not work. It just doesn't.
Although i have it working ok on USART2, i would still like to know why it doesn't work on USART1.
If anyone has a working bootloader for this chip on USART1 perhaps they can send in their code for comparison.
