I worry that it may bump back to software handled uart when it sees the invert.

Using INVERT on hardware UART
Posted: Sat Jul 03, 2004 12:25 pm
You cannot use INVERT with the hardware. You must use external inversion of some sort . If you reverse the normal XMIT and RECV pin designations I think it will generate a SW UART and not enable the HW one.

Another way to get a soft USART on the hardware pins is to break
up the #use rs232() declaration into two statements. Then you don't
have to reverse the pins. See this thread:
