Need sample for "when $XFERSTATUS" usage

[Taxi60]

I send a file to an ARM-Processor with RAWASCII. I first used "while $XFERSTATUS/yield" but the transfer slows down for this command.
Now I want to use "when $XFERSTATUS" but when I do the following:

when $XFERSTATUS call handlingprocedure

the procedure never is beeing called

Anybody have a sample for the usage?

Can you post your current script, or at least handlingprocedure?

One problem I've seen in the past is when statements being constantly run inside a while loop. If that applies to your main script, make sure the when command is not in any loops.
