Thanks for all of your help! I see now that my mistake was
interpreting "empty" as meaning "cleared."

Is there any reason to wait to write until TRMT is set as opposed to TXIF?

Isn't that unusual for an interrupt flag? Don't interrupt flags
generally have to be cleared, else the ISR will continually be called?
Does reading from the RCREG (like "variable =3D RCREG") clear the
interrupt flag, then?

Thanks,
