Definately confusing.  I changed it to set both those TRIS bits now.

I knew about that, but at this point, I'm just trying to get a signal on TX 
to make sure that part is working.  If bytes get lost it is not a problem 
yet.  I did change it to check that flag just in case my overflows were 
turning off the USART or something like that.

Now, TXIF is never being set, so I'm never even trying to transmit (and of 
course have no signal on TX).

Thanks,
