Can you tell us what you wrote, and what the result was, and what you expected from your code, because this statement has nothing to say for us.
Now it yust a sentence with no value.

You bought the software? and are reporting a BUG here? yes we suport all software here.....
lol funny things still happen:)

Did you report this post as a waste of time?

When compiled with pbp 5.xx or higher on the lines OWINOUT the micro stands and not continue the process, the same thing happens if you use SEROUT/SEROUT2. If you compile with pbp 2.47 then it works well.

Yep. There is a problem in the OWOUT library routine that causes a continuous loop if the
defined OSC > 8.

Open your pbppic14.lib. Scroll down to the OWOUT library routine.



Change this;

Code:
iorwf   INDF, F     ; Set to input then wait ~10us for recovery
    decfsz  R1 + 1, F   ; Do next bit, if any
  if (OSC >
    movlw    9          ; Delay 9us
    call     PAUSEUS
  endif
    goto     owoutloop

-----------------------------------------------------
To this;
Code:
    iorwf    INDF, F     ; Set to input then wait ~10us for recovery
   if (OSC >
    movlw    9           ; Delay 9us
    call     PAUSEUS
   endif
    decfsz  R1 + 1, F    ; Do next bit, if any
    goto    owoutloop

------------------------------------------------------------

decfsz R1 + 1, F needs to be after if (OSC > and just before goto owoutloop or you're stuck
in a nasty continuous loop whenver OSC > 8.
