Framing error if I disable transmitter after shift register is empty?

[Demon]

I'm using a 16F1937, and I've done this successully in the past on this PIC model.

Check this out, it's always after the last HSEROUT:

    TXSTA.5 = 1                     ' TXEN: Transmit Enable bit
    hserout ["1"]
    hserout ["2"]
    hserout ["3"]
    hserout ["4"]
    hserout ["5"]                             
    while TXSTA.1 = 0               ' Check TRMT: Transmit Shift Register Status bit
    wend
'    TXSTA.5 = 0                     ' <----- Causes Framing error after last byte !
