I just don't think CCS has it all working on the 12F1840. If you have
4.128, and you recently bought it, then you should be able to ask CCS to
add hardware UART support, and #pin select support i ... |

Update on the troubleshooting to Ttelmah's suggestions.
This code:
#byte APFCON=getenv(SFR:APFCON)
gave me an "Expression must evaluate to a constant" error.

I tested all four combinations of the Tx/Rx pins on the 12F1840, and the compiler generated a software UART for all of them. I also tried using "UART1" instead of specifying the pins. It s ... |

Thank you Ttelmah,
Worth the effort but I'm in square zero again. It didn't work.
The fact that this PIC has its own EUSART module is the clue that this feature works in a different way than usin ... |
