Hello Christian,

thx - that is how i detect a disconnect right now. i think that also -1 can be 
returned in case the other party has not read their receive buffer before the 
disconnect happend. (so i do check for dlen<=0 not dlen== 0).

But i would like to raise the question again: in which case will  
SocketPort::disconnect() be called?
My guess would be: in case of incoming OOB data but i might be wrong.

best regards

Wolfgang
