The TRMT bit tells you that all bits have finished going out.  The TXIF bit
in PIR1 indicates when the UART can accept another outgoing character.  This
happens as soon as TXREG is copied into TSR.  That gives you a whole
character time to react before there would be any break in the output
stream.
