Make sure you set the 'RThreshold' property to 0 in order to activate the OnComm Event. Build an event procedure in the onComm Event(do case.. endcase) to trigger the received event.

Hope can help.

BTW, I've a question. How to distribute the OLE control (*.OCX) with our application ? Assumed that the user site doesn't have VFP, VB.

Thanks
