Why not just put the rest of the interrupt handler right here?  Something
has to go here, and it might as well be the interrupt code.

This is probably not what you want to do.  You do need to make the
interrupt condition go away, but this is done by reading RCREG for the
UART receive interrupt.

Direct bank setting?

Indirect bank setting?

Bad idea.  This completely resets the UART receiver, which will cause it
to loose any new byte it might be in the middle of receiving, and it may
make it mistake a normal data bit for a start bit.
