Sorry, typo, UNTALK of course.

Quite logical indeed! But being so focussed on the source code, I
completely overlooked this :(
Thank you for the explanation!

But if there won't be a byte in the queue, why checking for it? Skipping
it would save some time but it would be peanuts compared to the whole
proces. Looking at the source code my first idea was: it saves some
bytes. But then: why setting ATN (L) at $EDF3 if it will be done at
$ED2E anyway? 

Another question: please have a look at the code starting from $ED21.
Why is the CLK set (H) when an UNLISTEN is going on but not for UNTALK?
