Status of running rsync

[Fabian Cenedese]

Hi

Is there a way to get the status of a running rsync process? I believe
it has to be done by sending a signal, but I can't find it anymore. I'd
like to find out if a rsync process is hung or just transferring a lot of
data.
This is rsync 3.0.3(I think pre1) on a NAS with BusyBox.

Thanks

bye  Fabi
